Industrial‐level Paired Electrosynthesis of Valuable Chemicals over a High‐performance Heterostructural Electrode

Paired electrosynthetic technology is of significance to realize the co‐production of high‐added value chemicals. However, exploiting efficient bifunctional electrocatalyst of the concurrent electrocatalysis to achieve the industrial‐level performance is still challenging. Herein, an amorphous Co2P@MoOx heterostructure is rationally designed by in‐situ electrodeposition strategy, which is acted as excellent bifunctional catalysts for the electrocatalytic nitrite reduction reaction (NO2RR) and glycerol oxidation reaction (GOR). The membrane‐electrode assembly (MEA) electrolyzer realizes a low voltage of 1.30 V, robust stability over 200 h at 100 mA cm‐2, high Faraday efficiencies and yield of NH3 (above 95%, 49.7 mg h‐1 cm‐2) and formate (above 95%, 152.3 mg h‐1 cm‐2) at industrial‐level current density of 500 mA cm‐2. In‐situ spectroscopy studies have shown that high‐valence CoOOH is the main active material of GOR, and the main catalytic conversion pathway of NO2RR involves key *NH2OH reaction intermediates. In addition, theoretical calculations confirm that the Co2P@MoOx heterostructure has strong interfacial electronic interaction and optimized reaction energy barriers, which endows its intrinsically high electrocatalytic activity for the co‐electrosynthesis of NH3 and formate.
