From: High yield electrosynthesis of oxygenates from CO using a relay Cu-Ag co-catalyst system
a FEs and b partial current densities for oxygenates over Cu and Cu-Ag composites under different applied current densities. c Cu/30Ag performance for oxygenates electrosynthesis under a CO flow rate of 5 SCCM. d TEA analysis. e The correlation between the applied current density and Ag content in Cu-Ag composites at their own maximum FE for oxygenates. f Ratios of FEOxygenates to FEEthylene and ratios of FEOxygenates to FEHydrogen over Cu-Ag composites at their own extreme points compared to these ratios of Cu at 400 mA cm−2. g Cu/30Ag CORR performances at the applied current densities of 1000, 1200 and 1400 mA cm−2 under 100 mL min−1 flow rate of the cathode electrolyte. h Stability evaluation of Cu/30Ag using MEA. Error bars correspond to the Standard Deviation (SD) of three independent measurements.
