Voltammetric measurements showed in the previous paper that charge transfer is accompanied with CO adsorption on Cu electrode. Adsorbed CO is present at Cu electrode surface below the potential of the cathodic charge transfer, and not present above the potential, as confirmed by infrared spectroscop

A~traet--CO~ reacts in acid solutions with chemisorbed hydrogen on platinum in the potential range of Eh = 0-250 mV to form a chemisorption product of reduced COs (perhaps CO). The rate of reduction on bright platinum at room temperature is very slow, taking more than 2 min at Eh = 0 for the total
Electrochemical reduction of Cot at metal electrodes yields CO, HCOO-, CH,, C,H,, and alcohols in aqueous media. Metal electrodes are roughly divided into two groups, CO formation metals (Cu, Au, Ag, Zn, Pd, Ga, Ni, and Pt) and HCOO-ones (Pb, Hg, In, Sn, Cd, Tl). Foreign atom modified electrodes (th
