Electrocatalysts for CO2 reduction are typically prepared and optimized ex situ before the reaction begins, but during reactions they may undergo changes that lower their performance. Here the authors show that active Cu catalysts can be formed on a recoverable basis and removed in situ during the CO2 reduction reaction, improving the stability of the system.
