Abstract

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.
