Recently， photocatalytic oxidation of pollutant in air with semiconductor photocatalyst is a hot spot in environmental science。 The feasibility study of photochemical active of degrade H2S by SiO2， WO3 doping on TiO2 thin film has been taken。 SiO2/TiO2 and WO3/TiO2 composite photocatalyst thin films have been made， and its purification capacity of H2S gas has been tested。 X-ray diffraction and scanning electron microscopy have been employed to describe the character。 Composite films of SiO2/TiO2 showed good removal efficiency of H2S more than TiO2 film about 8。59%。 The WO3/TiO2 composite films have photocatalytic activity with H2S gas purification in the visible light。 Theoretically H2S gas can be purification by WO3/TiO2 composite photocatalyst thin film under the visible light conditions。
