Abstract

The oxygen-deficient Ca₂Mn₂O₅ perovskite nanoparticles exhibit remarkably higher catalytic activity compared to CaMnO₃ and MnO₂ nanoparticles for photochemical water oxidation. The fraction of surface adsorbed hydroxyl groups on these catalysts has been suggested to be the dominant factors affecting water oxidation activity compared to the other parameters such as oxidation states of manganese and crystal structure.
