Abstract
The electrocatalytic oxidation of ethylene glycol (EG) at polycrystalline platinum in 1 M KOH was studied under potentiodynamic and potentiostatic conditions. EG electroadsorption processes were clearly distinguished from the oxidation of EG electroadsorbed residues by using the flux technique after adsorption. The maximum adsorption potential was between 0.3 and 0.4 V in the H-adatoms potential region. An electroadsorbed residue which oxidizes at more positive potentials was formed. The (eps) ads and (eps) ox values were independently determined by the potentiostatic i/t transients at 0.35 V and the potentiodynamic oxidation profiles at low sweep rates respectively. The experimental values obtained allowed to postulate a plausible reaction pathway sequence. The comparison of EG with electroadsorbed 1,3 dioxolane and adsorbed CO electrooxidation spectra showed similar surface oxidation behavior.
