a Full cell voltage on the function of the applied currents. b CO2R products distribution of PT/Cu and Nafion/Cu. c-d CO2R performance on (c) Sn NP and (d) Ag NP catalysts in a flow cell. For the MEA test, 1 M KOH was used as the anolyte with a flowrate of 3 sccm. The CO2 flowrate in the cathode side is 24 sccm. Before introducing CO2 into the MEA cell, it is passed through a sealed water container for preliminary humidification. For panel a, no iR correction was applied, for panels c and d, 100% iR correction was applied. Details regarding the iR correction can be found in the Method section. Relevant source data are provided as a Source Data file.
