Abstract

A two-step wet impregnation method was developed to synthesize a FeCuO_x bimetallic catalyst featuring a Cu₂O nanowire scaffold as a nanotemplate for anchoring Fe₂O₃ nanoparticles. The catalyst exhibits excellent NO₃RR performance in neutral electrolyte, achieving a faradaic efficiency of 90.3% and an NH₃ yield of 4609.6 µg cm⁻² h⁻¹, attributed to Cu–Fe interfacial electronic coupling that balances *NO₃ activation on Fe₂O₃ with *NO₂/*NH_x hydrogenation and NH₃ release on Cu₂O, thereby promoting rapid intermediate transfer and suppressing side pathways.
