Abstract
Abstract Green ammonia synthesis through electrocatalytic nitrate reduction reaction (eNO 3 RR) can serve as an effective alternative to the traditional energy‐intensive Haber‐Bosch process. However, achieving high Faradaic efficiency (FE) at industrially relevant current density in neutral medium poses significant challenges in eNO 3 RR. Herein, with the guidance of theoretical calculation, a metallic CoNi‐terminated catalyst is successfully designed and constructed on copper foam, which achieves an ammonia FE of up to 100% under industrial‐level current density and very low overpotential (−0.15 V versus reversible hydrogen electrode) in a neutral medium. Multiple characterization results have confirmed that…
