中文摘要 | The electrochemical activities of Ti based IrO2 active coating electrodes in Na2SO4 aqueous solutions containing methanol, formic acid and formaldehyde, respectively, were investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The activity was quantitatively characterized by the double-layer capacitance, C-dl. The results showed that in comporison with that in H2SO4 electrolyte the electrode activity in Na2SO4 solution with the same concentration declines dramatically. The active surface area of the electrodes was also found to decrease in the presence of these small organic moleculars. It was found that the electrooxidation of organic compounds can take place in a wide potential region, but with a slow reaction rate. The organic oxidation is facilitated by the oxygen evolution on this type of electrode. |
