a–c Cyclic voltammograms (CVs) of products detected by the Pt ring electrode during Cu catalyzed acetaldehyde reduction at pH = 4 (0.0001M HClO4 + 0.0999 M NaClO4), 7 (0.1 M NaClO4), 10 (0.0001 M NaOH + 0.0999 M NaClO4), respectively. Only the positive-going scans were shown for clarity. Cu disk potential was held from −0.5 V to −1.2 V. CV of the acetaldehyde blank was collected on the Pt ring when Cu disk was at open circuit potential (OCP). d–f Total Cu disk current during acetaldehyde reduction. CV conditions: 0 to 1.6 V and then back to 0 V (vs. RHE), 100 mV/s, 1600 RPM, 298 K.
