| 中文摘要: |
| 运用循环伏安法在光滑的铂电极表面上修饰了稀土多金属氧酸盐,并用交流阻抗进行了表征,研究了该电极对甲醇的电催化氧化行为。实验结果表明,与未修饰的光滑的铂电极相比,稀土多金属氧酸盐修饰的电极对甲醇电催化氧化速率明显增加。并测定了该修饰电极电催化氧化的动力学参数。 |
| 英文摘要: |
| Platinum electrode was modified with rare earth-polyoxometalate using cyclic approach and characterized by the electrochemical impedance spectroscopy(EIS)measurements. Electrocatalytic oxidation of methanol by modified electrode was studied. The results show that the platinum electrode modified with rare earth-polyoxometalate has promoting effects on the methanol electrochemical oxidation compared with the non-modified platinum electrode.In addition, the kinetic parameters of electrocatalytic oxidation of methanol by modified platinum electrodes were determined. |
