对1．0mol／LNiSO4和0．5mol／LH3BO3体系，控制电位为-1．25V，沉积60min，制得高择优取向镍电极．该镍电极经X射线衍射测定其织构度TC220为92％．采用循环伏安法研究了1mol／LNaOH溶液中高择优取向镍电极上丙醇的电催化氧化机理及活性，结果表明：高择优取向镍电极对正面醇的电催化活性高，对异丙醇的电催化活性小；推导出正丙醇的电氧化动力学方程，运用稳态极化曲线测定了其电氧化过程的动力学参数．Ni（Ⅱ）氧化为Ni（Ⅲ）的反应速度常数K1（E）＝5．25×10－13exp（0．488FE／RT），Ni（Ⅲ）还原为Ni（Ⅱ）的反应速度常数K-1（E）＝2．46×10-4exp（-0．512FE／RT），Ni（Ⅲ）氧化正丙醇的反应速度常数K2＝5．64×10－6L·mol-1s-1．
For the 1.0mol / LNiSO4 and 0.5mol / LH3BO3 systems, the control potential was -1.25V and the deposition time was 60min. The nickel electrode has a texture TC220 of 92% as determined by X-ray diffraction. Cyclic voltammetry was used to study the electrocatalytic oxidation mechanism of propanol and its activity on a nickel electrode with high selectivity in 1 mol / L NaOH solution. The results showed that the electrocatalytic activity of high selectivity oriented nickel electrode to alcohol was high, The catalytic activity of n-propanol was deduced. The kinetic parameters of electrooxidation of n-propanol were also determined by steady-state polarization curves. The reaction rate constant K1 (E) = 5.25 × 10-13exp (0.488FE / RT) for the oxidation of Ni (Ⅱ) to Ni (Ⅲ) 1 (E) = 2.46 × 10-4exp (-0.512FE / RT). The reaction rate constant K2 = 5.64 × 10-6L · mol-1s-1 for Ni (Ⅲ)
