Plots of differential charge analysis for *CO absorbed on Cu(111) surface (front view: a top view: b) and Cu0/Cu1+ interface (front view: c, top view: d). Blue, red and gray balls stand for copper, oxygen and carbon atoms, respectively. The yellow and blue isosurfaces correspond to the electron accumulation and depletion regions, respectively. e Schematic illustration of electrocatalytic equipment with the gas diffusion electrode for CO2RR. f Stability measurement of CO2RR for 28.5 h of electrolysis at an optimum potential of −0.71 V vs. RHE at 5% CO2 feed concentration and current densities for each product. There is no iR correction for voltages. Source data are provided as a Source Data file. Raw simulation data are provided as Supplementary Data 1 file.
