Oxygen Reduction Intermediates Facilitate Stable and Efficient CO2 Electroreduction to Multicarbon Products in an Acidic Electrolyte.
CO2 electroreduction in an acidic electrolyte with low alkali cation concentrations is an effective approach to mitigate the salting-out effect and achieve stable catalysis. However, the competitive hydrogen evolution reaction (HER) becomes more significant due to the high proton concentration. In this study, we introd...
