On copper catalysts, Cuδ+ sites play a key role in the electrochemical reduction of CO2 to C2 hydrocarbons, however, they are prone to being reduced (to Cu0) themselves. Now, a Cuδ+-based catalyst is reported that is stable for in excess of ~40 hours while electrochemically reducing CO2 to multi-carbon hydrocarbons and that exhibits a Faradaic efficiency for C2 of ~80%.
