Abstract

Abstract: Low‐cost, nonprecious transition metal (TM) catalysts toward efficient water oxidation are of critical importance to future sustainable energy technologies. The advances in structure engineering of water oxidation catalysts (WOCs) with single TM centers as active sites, for example, single metallic molecular complexes (SMMCs), supported SMMCs, and single‐atom catalysts (SACs) in recent reports are examined. The efforts made on these configurations in terms of design principle, advanced characterization, performances and theoretical studies, are critically reviewed. A clear roadmap with the correlations between the single‐TM‐site‐based structures (coordination and geometric structure, TM species, support), and the catalytic performances in water oxidation is provided. The insights bridging SMMCs with SACs are also given. Finally, the challenges and opportunities in the single‐TM‐site catalysis are proposed. Abstract : Focusing on single transition metal (TM) site catalysis, a clear roadmap with the correlations between the catalytic performances in water oxidation and the single‐TM‐site‐based structures including coordination and geometric structure, TM species, and support is provided. Bridging remarks between single metallic molecular complexes and single‐atom catalysts are also given.
