Abstract Electrocatalytic nitrate reduction reaction (NO 3 RR) provides a feasible strategy for green ammonia production and the treatment of pollution in wastewater. The generation active hydrogen (H*) plays an important role improving selectivity, yield rate, Faradaic efficiency products. Here, structurally ordered nanoporous Cu 6 Sn 5 ‐type high entropy intermetallics (HEI) with extremely superior performance toward NO RR is demonstrated. optimal (Cu 0.25 Ni Fe Co ) HEI delivers NH 97.09 ± 1.15% excellent stability 120 h at industrial level current density 1 A cm −2 , accordingly directly converting ‒ to high‐purity (NH 4 2 HPO near‐unity efficiency. Theoretical calculations combined experimental results reveal that multi‐site nature can simultaneously promote water dissociation, reduce reaction‐free energy hydrogenation process, suppress evolution. This work design precious‐metal‐free sustainable synthesis paves insights into H* enrichment mechanism.
