Remarkable effect of Pt nanoparticles on visible light-induced oxygen generation from water catalysed by perovskite oxides

Abstract

Oxidation of water is a challenging process with a positive free energy change and it is purposeful to find good catalysts to facilitate the process. While the perovskite oxides, LaCoO₃ and LaMnO₃, are good electron transfer catalysts in artificial photosynthesis to produce oxygen by the oxidation of water, the electron transfer is further favoured by the presence of platinum nanoparticles, causing a substantial increase in oxygen evolution.
