英文摘要	Metal oxide based solar thermal water splitting is a promising approach for using solar energy to produce H2 and O2. The normal protocol employed for this process involves thermal reduction of a metal oxide (MOx) at around 1500°C to produce the reduced form of the metal oxide (MOx-δ) and O2. This step is followed by steam treatment of MOx-δ at around 1000°C to yield MOx and H2. Owing to the need to use high temperatures, the traditional approach has several important drawbacks. In a study designed to improve this process, we found that Cu-loaded TiO2 (Cu/TiO2) effectively expels O2 upon irradiation with AM 1.5 1 Sun solar simulated light and that treatment of the reduced form of the reduction product Cu/TiO2-δ with steam at 140°C generates H2. This new approach, termed as solar photochemical-thermal water splitting, has the potential to become an important method for converting solar energy into chemical energy. © The Royal Society of Chemistry 2017.
