a FEs for H2 (gray), CH4 (blue), CO (green), and C2H4 (orange) production at pristine Cu, Cu-5thin, and Cu-5 electrodes. b FEs for H2 (gray), CH4 (blue), CO (green), and C2H4 (orange) production at pristine Cu, Cu-5, and Cu-5block electrodes. All bulk electrolysis experiments were conducted at an applied potential of −0.96 V versus RHE for 60 min in CO2-saturated 0.1 M KHCO3. Error bars correspond to the standard deviation of at least two independent measurements. Source data are provided as a Source Data file.
