摘要
采用析氢实验、线性电位扫描和交流阻抗法,研究了Zn电极、In电极和化学镀铟锌电极在碱性溶液中的析氢行为。结果表明:镀铟锌电极能提高锌表面的析氢过电位,有效抑制锌的析氢反应和锌在碱性溶液中的自腐蚀。锌表面的铟层越厚,这种抑制作用越强;但铟对锌在碱性溶液中的阳极行为影响不大。
Hydrogen evolution reaction on Zn, In and In/Zn electrodes in KOH solution were investigated by measurement of the volume of hydrogen evolution, linear sweep voltammetry and AC impedance. The results showed that the deposited indium could increase the over-potential of hydrogen evolution on zinc, so that the hydrogen evolution reaction and the corrosion of zinc in KOH solution were inhibited, but the anodic behaviors were influenced slightly. As the thickness of indium deposited on zinc increased, inhibition was stronger.
