Abstract: | Develop a photocatalyst system for solar energy conversion to electric energy or chemical energy is a topic of great interest for fundamental and practical importance. In this study, nitrogen-doped TiO2 with high hydrogen production by photocatalytic water splitting were prepared by microwave-assisted hydrothermal method using titanium sulfate as precursor in the presence of urea. The nitrogen doped TiO2 prepared in this study was pure anatase phase with a high surface area (372?m2?g?1) and showed a very high hydrogen evolution rate of water splitting reaction under UV light irradiation (4,386?μmol?g?1?h?1) and visible light irradiation (185?μmol?g?1?h?1) which was about 15?times higher than commercial TiO2 (Degussa P25). |
