| 摘 要： | 循环伏安实验表明,以多孔氧化铝膜为模板制备出的镍纳米线电极对乙醇的电化学催化氧化具有很高的催化活性.用强制对流流体动力学的方法求算出乙醇在镍纳米线电极上的电子传递过程的速率常数高于许多文献报导值,而电子传递过程的随后步骤的速率常数相近.

| Abstract: | The electrocatalytic oxidation of ethanol at the nickel nanowire electrode was investigated by cyclic voltammetry and the forced convection hydrodynamic method. The kinetic parameters of the reaction were measured and it was found that the rate constants of the electron transfer processes on the nanowire electrode were much higher than those reported in the literatures, but the rate constant of the step following the electron transfer process was comparable to the reported values. |
