A sustainable reaction of electrocatalytic nitrate conversion in ammonia production (NO3RR) occurring under ambient conditions is currently prime interest, as well urgent research due to the real potential replacement environmentally unfavorable Haber-Bosch process. Herein, a series electrocatalysts based on two-component cobalt alloys was synthesized using low-cost non-noble metals Co, Fe, Cr, and also Si. The samples were characterized studied by following methods: SEM, EDX, XRD (both transmission reflection), UV-VIS spectroscopy, optical microscopy, linear (and cyclic) voltammetry, chronoamperometry, electrochemical impedance spectroscopy. Beyond that, determination electrochemically active surface area carried out for all electrocatalysts. Unexpectedly, sample having an intermetallic compound (IMC) composition Co2Si turned be most highly effective. highest Faradaic efficiency (FE) 80.8% at E = -0.585 V (RHE) yield rate 22.3 µmol h-1 cm-2 -0.685 indicate progressive role IMC main component electrocatalyst. Thus, this study demonstrates promise enormous efficient NO3RR. This work can serve primarily starting point future studies reactions catalysts containing metals.

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.
