Abstract

The influence of Cu₂O and CuO to Pd/C electrocatalytic activities on ethanol electrooxidation in KOH solution was investigated. Pd/C, Pd-Cu₂O/C and Pd-CuO/C were synthesized and characterized by powder X-ray diffraction. The electrocatalytic activities were studied by Cyclic Voltammetry. The results show that catalytic activity of Pd/C for ethanol in KOH solution can be improved by Cu₂O and CuO. When the ratio of Pd to Cu₂O is 1:6 (w:w) and that of Pd to CuO is 1:1 (w:w), Pd-Cu₂O/C and Pd-CuO/C show the highest activity for the electrooxidation of ethanol in KOH solution, respectively.
