Published: Jan. 31, 2025

Diatomic catalysts are promising for the electrochemical CO2 reduction reaction (CO2RR) due to their maximum atom utilization and presence of multiple active sites. However, atomic-scale design diatomic elucidation synergistic catalytic mechanisms between centers remain challenging. In this study, heteronuclear Fe─In sites anchored on nitrogen-doped carbon (FeIn DA/NC) constructed. The FeIn DA/NC electrocatalyst achieves a CO Faradaic efficiency exceeding 90% across wide range applied potentials from -0.4 -0.7 V, with peak 99.1% at -0.5 V versus reversible hydrogen electrode. situ, attenuated total reflection surface-enhanced infrared absorption spectroscopy density functional theory calculations reveal that interaction Fe induce an asymmetric charge distribution, which promote adsorption site lowered energy barrier formation *COOH. Moreover, unique structure increase *OH through bridging interaction, decrease water dissociation further promoted CO2RR activity.
