Recent advances in the field of light-driven water oxidation catalyzed by transition-metal substituted polyoxometalates

Abstract

Transition-metal (TM) substituted polyoxometalates (POMs) have been demonstrated to be excellent water oxidation catalysts (WOCs) under visible light due to their unique structural features, tunable band gap structures and high stability. Herein, we present a brief review on recent developments in the field of TM substituted POM water oxidation catalysts (TSPWOCs) including both homogeneous and heterogeneous TSPWOCs. We systematically highlight the composition and structure of these different materials for higher photochemical performances and summarize recent advancements, which will provide readers valuable guidance for further discovery and improvements in efficient and robust TSPWOCs in future.
