• In order to develop a principle of the materials design for the high CO2 generation efficiency during the C2H5OH electrooxidation, the reaction pathways during the electrooxidation of C2H5OH and CH3CHO which is a by-product during the electrooxidation of C2H5OH have been quantitatively analyzed. As a result, a direct pathway from C2H5OH to CO2 and a pathway via CH3CHO toward CO2 coexisted at 0.4 V, 70°C. At 0.6 V, 70°C, the both pathways from C2H5OH to directly CO2 and from C2H5OH via CH3COOH to CO2 existed. Especially in the latter pathway, the activity of Pt was found to be deteriorated by the adsorbed species which would be formed as an intermediate of CH3COOH formation.
