Abstract Designing efficient and durable electrocatalysts for seawater splitting to avoid undesired chlorine evolution reaction resist the corrosive is crucial electrolysis technology. Herein, a functional bimetal (Co Fe) designed specifically modify nickel phosphide (denoted as CoFe‐Ni 2 P) boosting splitting, where Fe atom improves conductivity of Ni P improving electron transfer, Co accelerates self‐reconstruction process favorably generate co‐incorporated NiOOH (CoFe‐NiOOH) species on electrode surface. Additionally, these in situ‐generated CoFe‐NiOOH remarkably inhibit adsorption Cl − ions but selectively adsorb OH ions, which contributes excellent performance large‐current‐density splitting. Therefore, only requires low overpotentials 266 304 mV afford current densities 100 500 mA cm −2 harsh 6 m KOH + electrolyte, can work stably 600 h. Impressively, flow‐type anion exchange membrane electrolyzer assembled by P/Ni‐felt bifunctional demonstrated run at an industrially large density 1.0 A electrolyte 350 h, shows promising application prospects.
