a Schematic of the CO2 reduction reaction MEA system with IrOx and IrO₂ at the anode and Ag and Cu at the cathode. The cell voltage and Faradaic efficiencies for CO, C₂H₄, and H2 of (b) IrOx at the anode with (b) Ag or (c) Cu at the cathode and IrO₂ at the anode with (d) Ag or (e) Cu at the cathode in 0.1 M KHCO₃ at 300 mA cm–² for approximately 2 h (CP).
