Electrocatalytic reduction of NO2– to NH3 (NO2RR) offers an effective method for alleviating pollution and generating valuable NH3. Herein, a p-block single-atom alloy, namely, isolated Sb alloyed in Cu substrate (Sb1Cu), is explored as durable high-current-density NO2RR catalyst. As revealed by the theoretical calculations operando spectroscopic measurements, we demonstrate that Sb1 incorporation can not only hamper competing hydrogen evolution reaction but also optimize d-band center Sb1Cu intermediate adsorption energies boost protonation energetics NO2–-to-NH3 conversion. Consequently, integrated flow cell achieves outstanding yield rate 2529.4 μmol h–1 cm–2 FENH3 95.9% at high current density 424.2 mA cm–2, well durability 100 h electrolysis.
