G. Ritzoulis et N. Georgolios, EFFECT OF UNDERPOTENTIALLY DEPOSITED PB, TL, CD AND CU ADATOMS ON THEOXIDATION OF FORMALDEHYDE AT PD, Journal of electroanalytical chemistry [1992], 370(1-2), 1994, pp. 219-222
The effect of underpotentially deposited Pb, Tl, Cd and Cu on the oxid
ation of formaldehyde at a Pd electrode was studied. It was found that
these adatoms inhibit formaldehyde oxidation since they block active
sites on the electrode. Hence they prevent the formation of intermedia
tes, which are necessary for the oxidation to occur.
