Abstract Electrochemical nitrate reduction (NO 3 RR) offers a sustainable approach to mitigating nitrogen pollution while enabling the resourceful conversion of − ) into ammonia (NH ), gas (N 2 and value‐added chemicals such as urea. Copper (Cu)‐based catalysts, with their versatile catalytic properties cost‐effectiveness, have emerged pivotal materials in advancing NO RR. This review systematically summarizes recent progress Cu‐based catalysts for RR, focusing on mechanisms, tuning strategies, applications across diverse product pathways. The intrinsic self‐reconstruction behavior synergistic effects are elucidated alongside advanced situ characterization techniques that reveal dynamic structural evolution intermediate interactions during reactions. We comprehensively discuss performance steering RR toward NH or N production, emphasizing role catalyst design (e.g., single atoms, alloys, oxides, hydroxides) enhancing selectivity efficiency. Furthermore, multifunctionality Cu is exemplified through carbon–nitrogen (C–N) coupling reactions, where reactive intermediates valorized Key challenges future directions outlined guide rational systems efficient electrochemical cycling.
