Abstract During the electrocatalytic NO 3 − reduction reaction (NO RR) under neutral condition, activation of H 2 O to generate H* and inhibition inter‐H* species binding, are critically important but remain challenging for suppressing non‐desirable hydrogen evolution (HER). Here, a Mn‐doped Co(OH) (named as Mn‐Co(OH) ) has been synthesized by in situ reconstruction electrolyte, which is able dissociate molecules inhibits binding between each other owing increased interatomic spacing Mn‐doping. The electrocatalyst offers faradaic efficiency (FE) high 98.9±1.7% at −0.6 V vs. reversible electrode (RHE) an energy (EE) 49.90±1.03% NH production RR, among highest recently reported state‐of‐the‐art catalysts electrolyte. Moreover, negligible degradation −200 mA cm −2 found least 500 h, longest catalytic durations ever reported. This work paves novel approach design synthesis efficient RR electrocatalysts.
