Coupling Built‐in Electric Field and Lewis Acid Triggers the Lattice Oxygen‐Mediated Mechanism for Efficient Water Oxidation

) in 1.0 m KOH electrolyte. The catalyst maintains excellent activity in simulated seawater and 0.1 m KOH electrolyte. Furthermore, it demonstrates outstanding practical functionality, as the assembled commercial-scale alkaline electrolyzer operates stably for 50 h. This work may provide new approaches and theoretical insights for triggering and optimizing LOM.
