Electrocatalytic reduction of waste nitrate (NO3 -) in water represents a sustainable and economic route for selective electrosynthesis recycled ammonia (NH3), but their performance still falls behind the needed. Herein, bimetallic rhodium-copper nanocavities (RhCu NCs), featuring open mesoscopic structure well-alloyed composition at atomic level, are demonstrated as high-performance electrocatalyst efficient nitrate-to-ammonia --to-NH3) electrocatalysis neutral condition. In comparison to other counterpart electrocatalysts, best RhCu NCs deliver superior NO3 --to-NH3 very positive potential -0.10 V versus RHE with Faradaic efficiency 97.5%, yield rate 8.1 mg h-1 mg-1, energy 39%, cycling stability reaching 15 cycles. The combination kinetic analysis, situ Raman spectroscopy, density functional theory calculation reveals that active hydrogen radicals can be kinetically formed selectively consumed by nitrogen intermediates promote [2e + 6e] tandem pathway - NH3 electrosynthesis. work thus provides some insights into designing electrocatalysts multi-electron products from various electrocatalytic reactions.
