| 摘 要： | 采用气体收集实验、阴极极化曲线和电化学阻抗测量,研究了锌(Zn)和铋(Bi)电极在氢氧化钾溶液中的析氢反应。结果表明:Zn和Bi的析氢行为明显不同,当电位高于-1.92 V时,在相同电位下,Zn电极上收集的氢气体积、反应电流均大于Bi;而电位低于-1.92 V时,在相同电位下,Zn电极上收集的氢气体积及反应电流均小于Bi。

| Abstract: | Hydrogen evolution reactions on Zn and Bi in KOH solution were studied by the measurements of hydrogen evolution volume,cathodic polarization curves and alternative current impedance spectra.The results showed that the hydrogen evolution behavior on Bi was different from that on Zn.The hydrogen evolution volume and reactive current on Zn were larger than those on Bi at the same potential when the potential was more positive than-1.92 V.However,the hydrogen evolution volume and reactive current on Zn were smaller than those on Bi at the same potential when the potential was more negative than-1.92 V. |
