Electrocatalytic hydrogen evolution reaction(HER)is crucial for green hydrogen production and the transition toward low-carbon energy systems.However,the issues related to electrochemical gas bubbles,particularly at high current densities,have become a critical bottleneck for HER performance,resulting in active site isolation,increased ohmic resistance,and large concentration overpotential.Addressing these bubble-related limitations is therefore essential for advancing HER efficiency.This review aims to provide a comprehensive understanding of bubblemanipulation strategies for enhancing HER by(1)exploring the fundamental principles governing bubble dynamics at electrode interfaces,(2)presenting the strategies to mitigate bubblerelated issues at electrode interfaces,that is,passive strategies and active strategies,and(3)offering our insights into the challenges and opportunities for bubble dynamics in HER.By consolidating these projects,this review aims to advance the rational design of bubble management strategies and inspire innovative approaches for efficient hydrogen production. 展开更多

Precise control of adjacent-site proximity and electronic states in single-atom catalysts(SACs)enable atomic-level modulation of intrinsic catalytic properties.While the influence of electronic structure on catalytic performance is well established,the impact of adjacent-site proximity remains underexplored.Here,we report the single-atom platinum catalysts on MoS2(Pt-SAC/MoS2),in which both the controlled enrichment of adjacent Pt(Ptadj)sites and the Pt oxidation state are tuned via galvanic displacement of underpotentially deposited Cu adatoms.We find that hydrogen evolution reaction(HER)activity is predominantly governed by non-bonded Pt∙∙∙Pt proximity rather than oxidation state:enriched Ptadjsites in PtSA-0.1/MoS2exhibits a mass activity 41-fold higher than isolated Pt(Ptiso)sites in PtSA-0.3/MoS2under acidic conditions.In situ infrared spectroscopy reveals that Ptisosites preferentially bind linear adsorbed hydrogen intermediate(*HL),whereas Ptadjsites stabilize bridge hydrogen intermediate(*HB),which is indicative of adjacent-site proximity.Density functional theory calculations reveal that neighboring Pt atoms promote the formation of a three-center“Pt-H-Pt”bonding intermediate,which lowers the H-H coupling barrier and accelerates HER kinetics.These findings establish adjacent-site proximity as a dominant activity descriptor in SACs and provide new design principles for next-generation high-performance electrocatalysts. 展开更多

The ever-increasing consumption of fossil fuels has led to environmental crises,which accelerated the quest for sustainable hydrogen energy.Among various production routes,water electrolysis stands out as a promising approach.However,the efficiency of hydrogen evolution reaction is limited by the adhesion of gas bubbles on electrode surfaces,which blocks active sites,increases overpotential,and limits mass transfer.This review highlights the design of microanostructured array electrodes to achieve underwater superaerophobicity,reducing bubble adhesion,facilitating the nucleation and rapid release of ultrasmall bubbles,thereby contributing to reduce in overpotential,faster bubble growth,enhanced mass transport,and improved catalyst stability.We summarize recent advances in fabrication strategies of such electrodes,focusing on microanostructural designs,covering from 0 to 3-dimensional structures.Additionally,the role of hydrophilic gels in optimizing superaerophobicity is discussed.Finally,challenges and future directions are addressed,including bubble dynamics accurate modeling,development of high activity and stability catalysts,intelligent adaptive electrode structure and active bubble regulation,and the integration of artificial intelligence and deep learning for guided electrode design.This review aims to provide a comprehensive perspective on how superaerophobic electrode design address bottlenecks in gas-evolving electrodes,paving the way toward more efficient and economical hydrogen production. 展开更多

Regulating the critical process of proton migration from water dissociation for boosting alkaline hydrogen evolution reaction(HER)remains a challenge.Herein,we propose an electrostatic attraction strategy to achieve the migration of a highly efficient hydrogen species to Pt sites over Pt/Co@NC,which is obtained through a facile calcination and electrodeposition method.It exhibits an outstanding geometric activity(η10=31 m V),which surpasses the commercial 20 wt%Pt/C(η10=37 mV).Moreover,the mass activity of Pt/Co@NC is 5.6 A mgPt-1 at-50 mV vs.RHE,which is 2.23 times higher than that of 20 wt%Pt/C.Experimental and theoretical results indicate that the work function of the outer carbon layer,which is changed by the introduction of the inner cobalt core,plays a crucial role in reversing the direction of electron migration between the carbon layer and Pt.The negatively charged Ptδ-can spontaneously attract positively charged protons via the electrostatic interaction effect,thereby achieving the directional migration of hydrogen species.This work presents a strategy for designing advanced alkaline HER electrocatalysts by the electrostatic effect. 展开更多

The development of a high-performance pH-universal electrocatalyst for hydrogen evolution reaction(HER)is a vital step toward hydrogen economy but remains a major challenge.Herein,the Pd,Cu,and Ni three elements were confined in a nanoparticle via the microemulsion method.Morphology and structural analysis reveal that PdCuNi nanoparticles are nearly spherical in shape with slight aggregation,and are mainly composed of metallic Pd and Cu,as well as Ni oxide.The electrochemical tests show that PdCuNi exhibits favorable HER catalytic activity in acid(η10:45 mV;Tafel slopes:33 mV/dec)and neutral(η10:71 mV;Tafel slopes:87 mV/dec)media,and alkaline(η10:66 mV;Tafel slopes:116 mV/dec)media.The mechanism analysis implies that the synergistic effect of Pd,Cu,and Ni can improve the inherent conductivity of the catalyst and accelerate the charge transfer process.Furthermore,over 30 h long-term stability has been achieved without significant attenuation.This work provides a strategy for developing versatile and robust multimetallic catalysts towards pH-universal HER. 展开更多

The hydrogen evolution reaction(HER)is crucial for hydrogen production and sustainable energy storage.Molybdenum disulfide(MoS2),a representative transition metal dichalcogenides(TMDs),shows potential as an HER catalyst but suffers from limited performance due to poor charge transfer and interfacial effects.Here,we report a salt-assisted chemical vapor deposition(CVD)method for synthesizing high-quality tungsten ditelluride(WTe2)with tunable morphologies using alkali halides(NaCl,KCl and LiCl).The prepared WTe2 nanoribbons and hexagonal nanosheets exhibit morphology-dependent electrical conductivity,with nanosheets showing superior performance.To evaluate WTe2 as a contact electrode,WTe2−MoS2 heterostructures were fabricated and compared with graphene-MoS2 counterparts.The WTe2−MoS2 heterostructure exhibits a superior Tafel slope of 111.57 mV/dec and an overpotential of 298 mV at-10 mA/cm2,significantly outperforming graphene-based electrodes.This improvement is attributed to the excellent conductivity of WTe2 and reduced interfacial Schottky barriers.Moreover,we systematically investigate the influence of WTe2 thickness on HER performance and assess the electrochemical durability and structural stability of the heterostructure,further confirming the effectiveness of WTe2 as a contact electrode for enhancing the HER activity of MoS2.This study offers a novel approach for enhancing the HER performance of MoS2 through controlled WTe2 growth and application as a contact electrode.Our findings provide valuable insights into the synthesis of high-quality WTe2 and broaden the potential applications of two-dimensional materials in energy catalysis. 展开更多

Alkaline water electrolysis holds great promise for environmental remediation and sustainable energy conversion,yet its efficiency is hampered by the sluggish kinetics of the hydrogen evolution reaction(HER).Ru-based single-atom catalysts(SACs),with atomically dispersed active sites,offer enhanced catalytic performance.However,the development of Ru SACs is hindered by aggregation at high loadings and an obscured structure-activity relationship.In this work,we engineer Ru SACs supported on P,N self-doped carbon(PNC)derived from mushroom substrate residue through precise regulation of Ru content.This catalyst achieves stable Ru dispersion at loadings up to 2 wt%,thereby forming well-defined RuN3P1coordination structures.Density functional theory calculations reveal that the asymmetric Ru-N3P1 coordination modulates the electronic structure of Ru single atoms,facilitating both kinetically favorable water dissociation and thermodynamically balanced hydrogen adsorption,leading to superior HER activity.The optimized RuSAs/PNC-2wt%catalyst delivers exceptional alkaline HER performance,achieving an overpotential as low as 38 m V at 10 mA cm-2 and remarkable stability maintained over 325 h,attributed to its high density of accessible active sites and facilitated electron transfer kinetics.This study provides an effective strategy for constructing high-loading SACs and establishes a quantitative structure-activity relationship,guiding the design of advanced electrocatalysts for sustainable energy conversion. 展开更多

Electrocatalytic water splitting is a sustainable and environmentally friendly approach to hydrogen production, which is regarded as a promising alternative to traditional fossil fuels due to its high energy density and zero pollution. Despite its potential, the efficiency of this process is not yet satisfactory. In recent years, cerium(Ce)-based materials have become popular as electrocatalysts for water splitting,thanks to the variable valence of cerium and the numerous oxygen vacancies present in CeO2. These oxygen vacancies, along with the interface between CeO2 and metal components, can enhance the electronic structure and surface properties, thereby improving the performance of the hydrogen evolution reaction(HER). However, there is still a scarcity of research in this area. This article aims to provide insights into the recent progress made in using cerium for HER by examining different types of catalysts,to guide the design of Ce-based electrocatalysts that exhibit enhanced HER activity. 展开更多

The integration of multiple active sites has been demonstrated to significantly enhance the electrocatalytic performance of the hydrogen evolution reaction(HER).However,the precise construction of synergistic SAs/NCs sites and a thorough understanding of their reaction mechanisms remain challenging.Herein,a straightforward synthetic strategy is developed for the fabrication of Ru SAs and NCs supported on nitrogen-doped carbon spheres derived from m-aminophenol/formaldehyde resin(denoted as Ru1-n@AFCS),achieved by tuning the ratio of resorcinol to m-aminophenol during phenolic resin polymerization.The optimized Ru1-n@AFCS HER performance in alkaline media,requiring an overpotential of only 11.2 mV to achieve 10 mA cm-2 and displaying a mass activity of 5158.2 A g-1,which is 60 times higher than that of commercial 20%Pt/C(85.4 A g-1)at-0.025 V vs.RHE.When integrated into an anion-exchange-membrane water electrolyzer,the catalyst achieves a current density of 1 A cm-2 at 1.80 V with a remarkable noble metal mass activity of 55.2 A mg-Ru-1.Combined experimental and theoretical calculations reveal that the nitrogen-doped carbon support modulates electronic structure of Ru NCs,while adjacent isolated Ru SAs facilitate hydrogen transfer via strong hydroxyl adsorption,collectively forming a“dual-engine”catalytic center that significantly enhances alkaline HER performance. 展开更多

Molybdenum disulfide holds promise as a low cost and abundant catalyst for the hydrogen evolution reaction in an alkaline environment.However,its hydrogen evolution reaction activity is not sufficient for practical application because of its semiconducting properties in the 2H phase,presence of an electrochemically inert basal plane,and suboptimal hydrogen adsorption energy for hydrogen evolution reaction.In this article,we present a facile synthesis method for fabricating a Ni-doped molybdenum disulfide hydrogen evolution reaction electrode with a 1T structure through co-sputtering of molybdenum disulfide and Ni.Our results demonstrate that Ni doping not only promotes the 1T-phase yield in molybdenum disulfide structure but also activates the basal plane and improves the hydrogen adsorption energy of the edge plane.Also,the surface morphologies and 1T-phase yield,which are influenced by sputtering power and deposition time,are critical factors for the variation of hydrogen evolution reaction performance.Our Ni-doped molybdenum disulfide electrode,which exhibits high 1T yield and increased electrochemical surface area by tuning the morphology,shows an overpotential of -91 mV at 10 mA cm2,nearly 2.5 times lower than that of-227 mV observed for molybdenum disulfide.Also,the single-cell test exhibits enhanced cell performance with improved durability in the repetitive on/off evaluation for the potential application of renewable energy integration. 展开更多

The amorphization and heterostructuralization of noble metal-based materials are effective approaches to enhance the electrocatalytic performance towards the hydrogen evolution reaction(HER)in water splitting.Herein,(NH4)4[NiH6Mo6O24]·5H2O(NiMo6)polyoxometalate was employed for the Ru combination to fabricate a heterostructured catalyst consisting of amorphous RuMoNiNand crystalline Ni-MoO2(RuMoNiN/Ni-MoO2)via a simple annealing process under Ar/NH3atmosphere.Comprehensive structural characterizations and theoretical investigations suggest that the formation of such unique amorphous-crystalline heterostructures is governed by the application of NiMo6precursor and Ar/NH3atmosphere,which leads to the joint regulation on the electronic structure of Ru sites through-NH2 coordination and heterostructured interaction,and thus facilitating the water dissociation and H intermediates sorption steps in the alkaline HER process.Accordingly,the as-fabricated RuMoNiN/Ni-MoO2manifests excellent HER performance demanding an overpotential of only 18.3 mV at the current density of 10 mA cm-2with a minimal overpotential decay rate of 0.62 mV h-1during continuous operation at 1 A cm-2.This work offers constructive suggestions for the facile construction and structural regulation of amorphous-crystalline heterostructured noble metal-based electrocatalysts for various promising energy applications. 展开更多

Layered double hydroxides(LDHs)are attractive non-noble catalysts for overall water splitting(OWS),yet their hydrogen evolution reaction(HER)activity is often limited by suboptimal*H adsorption and a paucity of accessible sites.Herein,we introduce an oxygen-vacancy(Ov)engineering strategy to construct ultrathin Ni-Fe LDH nanosheets through one-step hydrothermal synthesis followed by mild NaBH4 etching.The resulting Ov-rich Ni-Fe LDH exhibits expanded interlayer spacing and abundant coordinatively unsaturated metal sites,as confirmed by XRD,XPS/O 1s deconvolution,and a pronounced electron paramagnetic resonance(EPR)signal at g≈2.003.Benefiting from the nanosheet architecture and defect modulation,the catalyst delivers an ultralow HER overpotential of 37 mV at 10 mA cm-2 and an oxygen evolution reaction(OER)overpotential of 315 mV at 50 mA cm-2.A two-electrode alkaline electrolyzer assembled from the same material achieves10 mA cm-2 at 1.54 V and sustains 500 mA cm-2 for>150 h with negligible decay,underscoring practical durability.In situ Raman reveals an earlier formation of the active NiFeOOH phase under anodic polarization,whereas DFT identifies Ni sites as the dominant centers and shows that Ov upshifts the d-band(HER)and downshifts it(OER)to optimize intermediate adsorption/desorption,lowering the rate-determining energy barriers.This study proposes a feasible approach for fabricating LDH-based electrocatalysts with enhanced catalytic performance in sustainable and clean energy conversion. 展开更多

Structural engineering of Pt-based nanoalloys is crucial for the rational design and manufacturing of high-performance and low-cost electrocatalysts for hydrogen evolution reaction(HER).Here,we reported PtNi nanoparticles with a refined size of 2.71 nm and regular strains loaded on carbon black,synthesized using the high-temperature liquid shock(HTLS)method.This approach offers significant advantages over conventional synthesis methods,including high scalability,rapid reaction rates,and precise control over the size and shape of nanocrystals.Importantly,the synthesized PtNi electrocatalysts demonstrate outstanding catalytic activity and long-term stability for HER,achieving low overpotentials of 19 and 203 mV at current densities of 10 and 1000 mA/cm2,respectively.The superior performance can be attributed to the combination of a refined particle size,lattice strains,and synergistic effects between Pt and Ni.This rapid liquid-state synthesis demonstrated here holds great potential for scalable and industrial manufacturing of micro-ano-catalysts. 展开更多

The hydrogen evolution reaction(HER)is a pivotal process for clean energy conversion,yet the development of efficient and cost-effective electrocatalysts remains a major challenge.Alloy catalysts,with their tunable electronic properties and promising catalytic performance,have shown great potential for HER.However,the design of component types and ratios,along with structural optimization,has largely relied on traditional trial-and-error approaches,which are very complex and time-consuming.The rise of machine learning(ML)provides an efficient strategy for discovering and optimizing alloy catalysts by enabling rapid analysis of extensive experimental and simulation datasets.This review highlights the recent advances in applying ML techniques for the design and optimization of alloy electrocatalysts for HER,covering binary and multinary(ternary,quaternary and high-entropy alloys).In particular,by employing supervised learning and deep learning techniques,ML has achieved remarkable success in the rapid screening of alloy catalysts and in improving prediction accuracy.It also demonstrates the merit and capability of ML in accelerating this process.In the end,we discuss current challenges and future prospects for integrating ML into advanced HER catalysis,highlighting its potential to revolutionize catalyst development and promote sustainable hydrogen energy solutions. 展开更多

The electrocatalytic CO2 reduction reaction(CO2 RR)offers a viable solution for the conversion and storage of renewable energy.Utilizing electronic metal-support interactions(EMSI)to adjust the electronic properties of metal catalysts has demonstrated effectiveness in enabling highly selective CO2 electroreduction.Here,a cleverly designed ternary composite is presented,which is synthesized by using nitrogen-doped hollow carbon spheres(NHCS)as the substrate and coating them with poly(3,4-ethylenedioxythiophene)(PEDOT)to form a PEDOT/NHCS support for anchoring Au nanoparticles.This innovative design enables the catalyst to reach a stunning 98.21% at-0.8 V versus RHE,achieving an extraordinarily high Faradaic efficiency for CO(FECO)over a broad potential window(-0.6 to-1.5 V vs.RHE).The result is mainly due to the Au-S bond between the S in the PEDOT thiophene ring and the metal Au,which induces electron transfer,causing the d-band center of the Au atoms to shift negatively.The hydrophobic surface of PEDOT and the hollow structure of NHCS synergistically construct an interface of“CO2-philic and H2O-phobic.”This interface,in coordination with the Au NPs,enhances CO2 adsorption,stabilizes the *COOH intermediate,accelerates the desorption of *CO,and simultaneously weakens the competitive adsorption of *H,effectively suppressing the HER. 展开更多

Engineering of the catalyst interface and modulation of transition-metal d-band play critical roles in the electrocatalytic hydrogen evolution reaction(HER).Herein,a synthetic strategy is developed to fabricate nitrogen‐doped carbon nanotubes(N-CNTs)-supported Ni3Se4-CeO2heterojunction catalysts through a facile chemical vapor deposition(CVD)process coupled with selenization.The heterojunction catalysts show excellent catalytic activity and stability for HER.Density functional theory(DFT)calculations reveal that Se modifies the electronic structure of Ni,CeO2regulates the interfacial charge distribution,and a multi-orbital coupling effect arises among the components.These synergistic effects collectively elevate the d-band center,thereby optimizing the free energy of the key adsorbed hydrogen intermediate(ΔGH*)in HER.Benefiting from the synergies between interface engineering and multi-orbital hybridization,the optimized Ni3Se4-CeO2heterojunction delivers a low overpotential of 180 mV at 100 mA cm−2,with a Tafel slope of 83.6 mV dec−1.The N-CNTs substrate further reduces charge-transfer resistance,thus promoting HER performance.Moreover,the confinement effect provided by cellulose acetate(CA)and the hydrogen-bonding network formed within the cotton substrate ensure outstanding long-term durability,as evidenced by sustained catalytic activity after 100 h of continuous operation at 100 mA cm−2.This work will offer a promising pathway toward the development of efficient heterojunction catalysts for HER via modulation of their electronic structure and interface. 展开更多

The potential to eliminate nitrate pollution in waste effluents by electrochemically reducing nitrate to ammonia has sparked global interest in developing highly active electrocatalysts for the nitrate reduction reaction(NO3 RR).Metal-organic frameworks(MOFs)have emerged as a promising candidate for creating the nextgeneration NO3 RR electrocatalysts due to their abundant active metal sites,electrical conductivity,and wellorganized porous structure.In this context,we report the synthesis and applications of a unique bimetallic MOF,i.e.,CuFe(x:y)MOF,as an efficient dual electrocatalyst for NO3 RR and hydrogen evolution reaction(HER).We have carefully adjusted the Cu to Fe ratio in CuFe(x:y)MOF to achieve the best possible result.The CuFe(1:2)MOF,with its distinct features,showed excellent NO3 RR with a high ammonia yield of 5.08 mmol/(h·cm2)and 87%faradaic efficiency.Moreover,the material demonstrated catalytic activity for the hydrogen evolution reaction,exhibiting an overpotential of 175 mV and a low Tafel slope of 295 mV/dec under optimized conditions.Further,chronoamperometry studies revealed that the catalyst remained stable for 24 h.These findings underscore the potential of the CuFe(x:y)MOF as an efficient dual electrocatalyst and a significant step forward in developing next-generation catalysts. 展开更多

The development of efficient electrocatalysts for the alkaline hydrogen evolution reaction(HER)remains a key challenge for hydrogen energy conversion.Here,we report a Cu-substituted Ru nanoparticle catalyst in which atomically dispersed Cu(0.31 wt%)is substituted into Ru nanoparticles(3.54 wt%)supported on oxygen-deficient ceria(Cu1–Ru/CeOx).This catalyst exhibits outstanding alkaline HER performance,delivering a low overpotential of 47 mV at 10 mA cm−2,a small Tafel slope of 43 mV dec−1,and a high mass activity exceeding 3.0 A mgRu-1,outperforming commercial Pt/C.The catalyst retains 95%of its initial activity after 100 h of continuous operation.Spectroscopic,structural,and DFT analyses reveal an asymmetric interfacial charge distribution:charge transfer from Cu to Ru generates electron-rich Ru and electron-deficient Cu1,while electron donation from Ru to ceria forms Ce3+ and oxygen vacancies.This tri-functional interface enables efficient water dissociation at Ce3+–Ov sites,optimized hydroxyl adsorption/desorption on electron-rich Ru,and weakened H binding on electron-deficient Cu1,thereby promoting H2 release.When paired with a RuO2 anode,the Cu1–Ru/CeOx(−)║RuO2(+)electrolyzer surpasses Pt/C(−)║RuO2(+)in full-cell efficiency and long-term stability,highlighting the importance of interfacial charge modulation and multi-site cooperativity in alkaline HER catalysis. 展开更多

Available online Alkaline water electrolysis(AWE)is a prominent technique for obtaining a sustainable hydrogen source and effectively managing the energy infrastructure.Noble metal-based electrocatalysts,owing to their exceptional hydrogen binding energy,exhibit remarkable catalytic activity and long-term stability in the hydrogen evolution reaction(HER).However,the restricted accessibility and exorbitant cost of noble-metal materials pose obstacles to their extensive adoption in industrial contexts.This review investigates strategies aimed at reducing the dependence on noble-metal electrocatalysts and developing a cost-effective alkaline HER catalyst,while considering the principles of sustainable development.The initial discussion covers the fundamental principle of HER,followed by an overview of prevalent techniques for synthesizing catalysts based on noble metals,along with a thorough examination of recent advancements.The subsequent discussion focuses on the strategies employed to improve noble metalbased catalysts,including enhancing the intrinsic activity at active sites and increasing the quantity of active sites.Ultimately,this investigation concludes by examining the present state and future direction of research in the field of electrocatalysis for the HER. 展开更多
