Abstract Water electrolysis in alkaline media, demonstrating robust facility and cheap electrolyzer construction, are regarded as a promising strategy for industrial green hydrogen generation. Exploring effective evolution electrocatalysts is remained an obstacle to date, which requires additional effort obtain active by water dissociation promote the following unfavorable coupling further H 2 release. Herein, MoO supported RuNi nanoparticle (RuNi‐MoO ) constructed efficient electrocatalyst evolution. Experimental theoretical analysis demonstrate that optimized built‐in electric field at interface between alloy simultaneously accelerates kinetics spillover. It attains current densities of 10 100 mA cm −2 ultralow potential −0.019 −0.086 V versus RHE, respectively, along with rapid cleavage kinetics, even surpasses commercial Pt/C. The constructing anion exchange membrane adopting RuNi‐MoO cathode density 1 A low voltage 1.71 steadily operates over 1000 h large .
