摘要In this paper,the nanometer TiO2-SiO2 composite oxide,which has a higher surface area,was prepared by sol-gel.The surface area and structural property of composite oxide were examined.The results indicated that nanometer particles of the composite oxide were obtained.When nSi∶nTi ratio was equal to 4.6,the surface area was larger comparing with pure TiO2 and pure SiO2.Tris(2,2’-bipyridine) ruthenium(Ⅱ) absorbed on TiO2-SiO2 composite oxide was sensitive to oxygen.
