The electrocatalytic oxidation of ethanol on Pd/GC, Pt/GC and Pd-Pt/GC alloy electrodes prepared by electrodeposition was studied in alkaline medium (1. 0 mol•L-1 NaOH). The experimental results show that a synergism was observed on Pd-Pt/GC alloy electrodes for the electrocatalytic oxidation of ethanol——yPd =0. 336 Pd-Pt/GC alloy electrode demonstrates the highest activity, the corresponding exchange current density is more than 30 times greater than that on Pure Pt/GC electrode.

Key words: Electrodeposition, Electrocatalytic oxidation, Ethanol
