摘要
NiMnO3 was found to be an efficient catalyst for light-driven water oxidation using [Ru(bpy)(3)](2+) and S2O82- as a photosensitiser and a sacrificial oxidant, respectively. NiMnO3 exhibited remarkably high catalytic activity in comparison with manganese oxides and nickel oxide. For electrochemical water oxidation, the highest catalytic current was also obtained with NiMnO3 among the manganese oxides.
