摘要

Ag/TiO2 photocatalytic films were produced by hybrid sol-gel method.The photocatalytic degradation of methyl orange (MO) in aqueous solution under 365 nm irradiation on TiO2 and Ag/TiO2 thin films was investigated.The state and amount of Ag species within the film and the enhancement mechanism of photocatalytic activity of Ag/TiO2 were discussed.With a loading molar ratio of Ag/Ti = 0.135 in TiO2 film,the maximum catalytic efficiency was observed.
