Özet

The electrocatalytic oxidation of ethylene glycol has been investigated on platinum-palladium alloy electrodes of different compositions in alkaline aqueous solution. The surface characteristics of the alloys in contact with electrolytic solution have been studied using cyclic voltammetry. X-ray diffraction studies are interpreted to verify homogeneity of electrolytically co-deposited alloys. Enhanced electrocatalytic activity at about 20 at.% in Pd is obtained when compared to pure metals, thus leading to a synergistic effect. An explanation of these effects is suggested on the basis of a decrease of strongly bound residue of ethylene glycol.
