| Abstract | Visible light responsive TiO2 (Vis-TiO2) thin films were successfully developed by the radio-frequency magnetron sputtering method, and their photocatalytic activities for the water splitting reactions were investigated. Pt-loaded Vis-TiO2 thin films acted as photocatalysts to decompose water involving sacrificial reagent such as methanol or silver nitrate under visible light irradiation (λ³ 420 nm). Furthermore, the separate evolution of H2 and O2 was successfully achieved under solar light irradiation by applying these photocatalysts in a H-type glass container, which consists of two water phases separated by a TiO2 thin film and proton-exchange membrane. |
