Abstract Despite recent achievements in the co‐reduction electrosynthesis of urea from nitrogen wastes and CO 2 , selectivity yield products remain fairly average because competition NITRR, RR, HER. Here, a strategy involving FeNC catalysts disperse with oxygen‐vacancy‐rich CeO (FeNC‐Ce) is illustrated, which reversible hydrogenation defects, bimetallic catalytic centers enable spontaneous switching between reduction paths NO 3 − . The FeNC‐Ce electrocatalyst exhibits an extremely high Faraday efficiency (FE) 20969.2 µg mg −1 h 89.3%, respectively, highly superior to most reported values (maximum 200–2300 FE max 11.5%–83.4%). study findings, rationalize by situ spectroscopy theoretical calculations, are rooted evolution dynamic NITRR RR protons, alleviating overwhelming single‐system reactants thereby minimizing formation by‐products.
