| 摘 要： | 采用线性电位扫描（LSV）、交流阻抗（EIS）方法研究了在硫酸溶液中不同锌含量的铅锌合金电极上氧气的析出。线性电位扫描实验数据显示，析氧电流随着锌含量增加而有所增大。交流阻抗法表明，随锌含量的增加铅锌合金电极上的析氧电化学反应电阻减小，电容增大，掺锌有利于氧气的析出。

| Abstract: | Oxygen evolution behavior on Pb-Zn alloys in sulfuric solution was studied by using linear sweeping vohammetry （LSV） and electrochemical impedance spectroscopy （EIS） . The results of linear sweeping volt ammgtry showed that electrical current of oxygen evolution can increase with zinc content increasing; electrochemical impedance measurements indicated that electrochemicat resistance of oxygen evolution can reduce with zinc content increasing, so zinc can accelerate oxygen evolution. But zinc content had little impact on oxygen evolution behavior. |
