Figure 2

Inhibition of CODH ICh by CO. Different partial pressures of CO were introduced into the electrochemical cell to measure product inhibition. As the CO concentration increases, the electrocatalytic current for CO2 reduction decreases. The inset enlarges the region in which CO2 reduction occurs. Experimental conditions: 25 °C, 0.2 M MES buffer (pH 7.0), rotation rate 3500 rpm, scan rate 10 mV/s.
