Abstract Seawater, as one of nature's most plentiful resources, provides a virtually inexhaustible source for generating hydrogen via water electrolysis. Developing an efficient bifunctional electrocatalyst direct seawater splitting is challenging but highly desirable. Herein, donut‐shaped Mo‐doped Ni 2 P nanoring developed, which promising overall splitting. The optimized Mo 0.1 1.9 catalyst shows low overpotentials and Tafel slopes in addition to high turnover frequencies, mass activities, exchange current densities. P||Mo couple‐based electrolyzer requires cell voltage only 1.45 V 1.0 m KOH 1.47 untreated alkaline real electrolysis at 10 mA cm −2 density. Industrially required densities 500 1000 are achieved record voltages 1.81 1.86 V, respectively, 25 °C 1.77 1.82 75 exhibited long‐term stability 400 during synergy between ions with multiple oxidation states ions, morphology play crucial role increasing active sites enhanced dissociation. This work highlights the potential nanorings unique catalysts
