Abstract Ambient electrocatalytic reduction of NO 2 − to NH 3 (NO RR) provides a reliable route for migrating pollutants and simultaneously generating valuable 3. However, the RR involves multistep electron transfer complex intermediates, rendering achievement high selectivity major challenge. In this contribution, heterostructured Cu O/NiO nanoflowers are explored incorporating advantages dual active sites as highly selective catalyst. Combined theoretical calculations in situ FTIR/EPR spectroscopy analysis, it is revealed synergistic effect O NiO promote energetics heterostructure electrocatalyst through tandem catalysis pathway, where activates initial absorption deoxygenation boosting * formation, while generated on then transferred substrate with abundant hydrogen conversion. Moreover, formation enhances H retention capacity, promoting consumed inhibiting inter‐ species binding. As result, equipped flow cell displays superior yield rate 128.2 mg h −1 cm −2 Faradaic efficiency 97.1% at current density −1.25 A . Further, designed system proven be adaptable other electrochemical production reactions including reduction.
