The electrocatalyst composed of Cu nanoparticles and g-C₃N₄ nanosheets (Cu−CN) is reported, which could efficiently covert CO into acetate with a Faradaic efficiency of 62.8 % in a flow cell and acetic acid continuously in a porous solid electrolyte reactor. In situ experiments and density functional theory studies reveal the synergy between dual catalytic regions: Cu/C₃N₄ interface enhances the generation and coverage of *CHO from CO, and Cu NPs facilitate the acetic acid (acetate) generation from migrated *CHO.
