Abstract The electrochemical reduction of nitrate to ammonia (NO 3 RR) has emerged as a promising but challenging orientation in sustainable development. Cu is one the most effective NO RR catalysts. However, accumulation 2 − on their surface erected bars further improvement efficiency. Herein, Cu‐based electrocatalyst with low‐coordinated atoms (Cu‐LC) synthesized via instantaneous ablation and rapid cooling target by pulse laser proposed new electrocatalyst, which exhibits enhanced activity NH selectivity 97.01%, yield rate 0.624 mmol h −1 cm −2 at −0.8 V versus RHE long‐term durability, superior reported introduction sites upshifts d‐band center near Fermi Level, enhancing adsorption key intermediates ( * , NO) RR, also effectively regulating generation hydrogenation process, inhibiting Cu‐LC surface, thus achieving efficient production. Furthermore, when evaluated cathode material Zn–NO battery, an open circuit voltage 1.3 power density 3.1 mW are achieved Cu‐LC‐based highlighting multifunctional system for production energy supply.
