The electrocatalytic NO reduction reaction enables sustainable NH3 synthesis and NO removal but faces challenges in achieving industrial-level efficiency and durability. Here the authors present an in situ-formed copper nanowire array monolithic electrode integrated into a pressurized electrolyzer for stable ammonia electrosynthesis at around 1000 mA cm–2 for 100 h.
