The production of high-concentration products and long-term stability are two major issues in the realization of the electrocatalytic CO2 reduction. Here three-dimensional Cu foam is used as a high-flux substrate in a catholyte-free membrane electrode assembly for the synthesis of 4.5 M formate for over 8,000 hours.
