Abstract Green hydrogen energy, as one of the most promising energy carriers, plays a crucial role in addressing and environmental issues. Oxygen evolution reaction catalysts, key to water electrolysis production technology, have been subject durability constraints, preventing large‐scale commercial development. Under high current density harsh acid‐base electrolyte conditions reaction, active metals catalysts are easily converted into high‐valent soluble species dissolve, leading poor structural catalysts. There is an urgent need overcome challenges under acidic develop electrocatalysts with both catalytic activity durability. In this review, latest research results analyzed depth from thermodynamic kinetic perspectives. First, comprehensive summary deactivation state process noble metal oxide presented. Second, structure possessing discussed. Finally, four new strategies for preparation stable “electron buffer (ECB) strategy”, combination strength control, strain surface coating, summarized. The prospects also elaborated future synthesis more effective Ru/Ir‐based boost their application.
