| Abstract: | The processes of adsorption and oxidation of methanol on Pt electrodes are studied by using Cyclic voltammetry and electrochemical quartz crystal microbalance (EQCM). The results demonstrate that the oxidation of methanol depends strongly on oxidation states of electrode surface, and that CH3OH is oxidized via a dual path reaction mechanism. The EQCM studies provided quantitative results of surface mass variation during methanol oxidation, and has thrown new light in elucidating methanol oxidation. |
