Efficient nitrate electroreduction over Mn-doped Cu catalyst via regulating N-containing intermediates adsorption configuration

The electrochemical reduction of NO3− to NH3 holds promise for economic and environmental benefits, presenting an energy-efficient alternative to the traditional Haber–Bosch method. However, challenges exist due to its sluggish kinetics, multiple intermediates, and various reaction pathways. In this study, Mn-doped-Cu catalyst was synthesized and employed for electrochemical NO3−-to-NH3 conversion. The doping of Mn into Cu resulted in exceptional performance, achieving a FE of 95.8
