📄 Abstract（原文）
Abstract Electrocatalytic processes for green energy production are of growing importance as they offer efficient energy conversion while maintaining environmental sustainability. In this context, transition metal oxyhydroxides (TMOxHy) have emerged as highly promising electrocatalyst candidates due to their intrinsic oxygen redox activity, structural robustness, and abundance of earth-derived elements. This review comprehensively examines the important characteristics and requisite strategies of TMOxHy materials, emphasizing their critical influence on catalytic performance. Various enhancement approaches-including surface and compositional modulation, elemental doping with transition metals, non-metals, and carbon-based species, cocatalyst integration, heterostructure engineering, and nanostructuring-are systematically evaluated for their roles in improving catalytic activity and durability. In addition, the electrocatalytic behavior of TMOxHy materials across diverse electrolyte systems is analyzed. Finally, key challenges such as charge transfer limitations, long-term operational stability, and electrode corrosion are discussed, and future perspectives for advancing TMOxHy -based electrocatalysts toward sustainable energy conversion technologies are proposed.
