The development of efficient catalysts for water oxidation is pivotal for advancing sustainable energy technologies, such as overall water splitting and carbon dioxide reduction. While molecular catalysts offer precise tunability at the atomic level, their practical application is hindered by instability and poor recyclability. Recent advances in metal covalent organic frameworks (MCOFs) have bridged homogeneous molecular catalysts and robust heterogeneous materials, offering a promising platform for durable water oxidation. This review highlights recent progress in the development of MCOF-based water oxidation catalysts, with a focus on design strategies, structure-activity relationships, and mechanistic insights.
