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.

Abstract 2D organic semiconductors are widely considered superior photocatalysts due to their large basal planes, which host abundant and tunable reaction sites. However, here, it is discovered that these planes can be pseudo‐inert, fundamentally challenging conventional design strategies assume uniform activity on the surface of semiconductors. Using potassium‐poly (heptazine imide) (KPHI) for hydrogen peroxide photocatalysis as a model, demonstrated pseudo‐inertness stems from preferential exciton transport edges, instead interlayer in highly ordered structures. Thus, dimension reduction enables controlled localization self‐trapping mechanism, whereby transform pseudo‐inert state into active catalytic With this knowledge, modified KPHI capable generating 35 mmol g −1 h H 2 O , over 350% increase compared pristine KPHI, reported. More interestingly, activated promote production through pathway distinct planes. These findings establish fundamental principles connecting crystal structure, dynamics, reactive site distribution, providing new insights high‐performance photocatalysts.
