摘要	The presence of oxygen species on the surface of Cu oxides can improve carbon dioxide (CO2) adsorption and lower the binding energy of oxygenic intermediates, thereby increasing the first-step reduction products of CO2 electro-reduction. Herein, the residual oxygen on Cu2O was stabilized using Sn2+ during the reduction process, and the retention of residual oxygen was confirmed using an in-situ Raman spectrum (Cu-O-ads). Simultaneously, in-situ Raman and density functional theory calculations revealed that the adsorption energy of carbon monoxide intermediate (*CO) on SnO/Cu2O catalyst was considerably lower than that on bare Cu2O catalyst due to the presence of residual oxygen. This resulted in an increased Faradic efficiency of 97.5% for CO production at a relevant potential of -0.8 V (vs. reversible hydrogen electrode). The oxygen stabilizing strategy for Cu oxide catalysts is inspiring in designing high-performance catalysts for CO2 electroreduction.
