Figure 2

Cyclic voltammograms of CODH adsorbed on (A) PGE, (B) NiO, and (C) TiO2. Current–potential curves of the bare electrodes are depicted in black; experiments with adsorbed CODH (recorded with a 50% CO/50% CO2 gas mixture bubbling through the cell) are shown in red. The blue CVs in (B) and (C) were recorded in the presence of 10 mM KCN (B) and 20 mM KOCN (C). Other conditions: T = 20 °C, 0.2 M MES buffer (pH 6), scan rate = 10 mV s−1. (A) and (C) are adapted from ref 15.
