ABSTRACT Bimetallic nanoparticles (NPs) are recognized as effective catalysts for the nitrate reduction reaction (NO 3 – RR) to produce ammonia (NH ) due their multiple active sites and electron redistribution enabled by strong metal–metal interactions. An in‐depth analysis of mechanism is essential advancing efficient electrocatalysts. In this study, carbon‐supported Au Cu alloy (Au Cu/CC) were synthesized applied direct NO − NH . The generation rate achieved with Cu/CC was 1719.3 µg h −1 cm −2 , Faraday efficiency (FE) measured at 95.1% under an ultra‐low potential −0.5 V versus RHE. high activity attributed synergistic interactions between in relay catalysis, where exhibits selective *NO, while demonstrates excellent performance subsequent *NO Additionally, d–d orbital hybridization adjusts d–band center NPs, effectively modulating adsorption energies *N facilitate This electrocatalytic approach offers a novel strategy designing multifunctional RR catalysts.

Abstract CO 2 electroreduction reaction (CO ER) provides a promising pathway for scaling up the conversion of to using renewable electricity, thereby providing an alternative potential carbon neutrality. Typically, conducted in aqueous media is ideal way on standpoint sustainability. However, undesired hydrogen evolution (HER) feasible occur catalyst surface together with ER, reducing overall ‐to‐CO efficiency. In this work, we utilized stacked structure N‐doped Ti 3 C T x MXene material supported metal oxide (ZnO) form ZnO/N‐Ti electrolytic reduction CO. The exhibited Faradaic efficiency (FE ) 96.4 % ER at −0.967 V ( vs . RHE) current density 7.2 mA cm −2 ZnO acted as active site , while was responsible enhancing textural properties and electrical conductivity, which could promote mass transfer gas molecules electron sites, further improving activity. This work inspires rational design unique oxide/N‐Ti interfaces regulate high‐performance electrocatalytic selectivity reduction.
