| 摘 要： | 采用析氢实验、线性电位扫描和交流阻抗法,研究了锌、铟和锌铟合金电极在碱性溶液中的电化学行为。结果表明,合金中的铟能提高锌表面的析氢过电位,有效抑制缓解锌上的析氢反应和锌的阳极氧化,从而抑制锌在碱液中的自腐蚀。合金中铟的含量越高,这种抑制作用越强。此外,合金中的铟能扩大锌的活化电位区,有效改善锌在KOH溶液中的放电性能。 |

| Abstract: | Electrochemical behavior of Zn, In and Zn-In alloy electrodes in KOH solution was investigated by measuring the volume of hydrogen evolution, linear sweep voltammetry and AC impedance. The results show that indium in Zn-In alloy can increase the overpotential of hydrogen evolution on zinc, which can effectively inhibit the hydrogen evolution reaction of Zn and the anodic oxidation of Zn in KOH solution, and the self-corrosion of Zn in alkaline solution can also be inhibited. As the content of indium in Zn-I... |
