| Abstract: | Thin-bounded CdS compounded TiO 2 films can promote the visiblelight-photocatalytic degene-ration efficiency of glass surface greatly. CdS compounded TiO 2 films are prepared by sol-gel method using spinning technique, and 90nm-thick films are obtained after two-layer coated.The morphology of glass surface is observed through SEM. The influence of compounding on the photocatalytic degeneration efficiency of TiO 2 films under visible light for oleic acid and acetic acid is investigated by high-pressure liquid chromatography. |
