Abstract Regulating the metal‐support interaction of anchored metal nanoclusters is recognized as valid approach to optimize electrocatalytic performance through tuning interfacial electronic structure. However, developing novel support and understanding electron accumulation on modulating reaction kinetics are still elusive. Herein, highly‐dispersed Ruthenium (Ru) onto phosphorous doped molybdenum boride (Ru/P‐MoB) developed ultrafast microwave‐plasma (60 s) approach. The synthesized Ru/P‐MoB impressively promote hydrogen evolution with low overpotentials 34, 45, 40 mV drive 10 mA cm −2 in alkaline freshwater, seawater acid media. Specially, it presents superior turnover frequency mass/specific activity relative Pt/C, Ru/C, Ru/MoB. Moreover, anion exchange membrane (AEM) electrolyzer cell based can achieve 500 1000 small voltages 1.71 1.78 V good durability. Experimental density functional theoretical (DFT) analysis reveal that strong interactions (Ru─Mo Ru─P bonds) generated electron‐enriched Ru, then favoring water‐molecule adsorption/dissociation optimal H intermediate adsorption free energy. This work provides designing avenue exploit electrocatalysts outstanding catalytic under high current at practical high‐temperature.
