Ammonia (NH3) is an ideal green fuel with high energy density and plays indispensable role in fertilizer production. Electrochemical reduction of nitrate (NO3–), a toxic pollutant groundwater, has shown promising as viable approach to converting waste into valuable NH3 under ambient conditions, offering alternative the energy-intensive Haber-Bosch process. Due their efficiency, copper (Cu)-based materials have great potential electrocatalysts for NO3– reaction (NO3–RR) NH3. In this review, we provide comprehensive summary fundamental principles underlying over Cu-based discuss various strategies enhance performance reduction, including facets, morphologies, size, surface functionalization, compositional engineering, defect engineering. We also delve relationship between electrocatalytic structure characteristics thoroughly examine mechanism involved NO3–RR. Furthermore, highlight existing challenges prospective paths forward area study. This review offers insights guidance strategic design optimization NO3–RR applications.

Electrochemical nitrate reduction reaction (NO3RR) offers a promising alternative for ammonia production using electricity generated from renewable energy sources. Active electrocatalysts with high selectivity and yield are required to selectively catalyze NO3RR ammonia. Here, P-doped Cu0.51Ni0.49 alloy thin films electrodeposited deep eutectic solvent of choline chloride-ethylene glycol (ChCl/EG). The P-Cu0.51Ni0.49 produces 1616.94 µg h-1 cm-2 at -0.55 VRHE (V versus reversible hydrogen electrode), Faradaic efficiency 98.38% 97.84% -0.25 VRHE, much better than the P-Ni P-Cu prepared under similar condition. rate, originated number electrochemically active sites more facile kinetics. Mechanistic study density functional theory calculation proves that exhibits higher conductivity NO3 - adsorption compared P-Cu, induced by electron interaction. Characterizations after cycling show crystallinity decreases, content divalent metal ions increases surface. is an stable material electrocatalyze in neutral aqueous solutions.
