摘要
采用线性电势扫描伏安法、循环伏安法和交流阻抗法研究了不同浓度硫酸铈的硫酸溶液中铅锑合金电极的电化学特性。实验结果表明:硫酸溶液中铈离子(Ce3+)的添加,抑制了铅锑合金电极上氧化膜中Pb(Ⅱ)的生成,提高了氧化膜的导电性;并且提高了电极析氧过电位,抑制了氧气的析出;同时也抑制了铅锑合金电极的腐蚀,提高了电极的耐腐蚀性能,改善了PbSO4/PbO2转化反应的可逆性。
The influence of cerium ion in sulfuric acid solution on the electrochemical properties of the lead-antimony alloy electrode was studied by linear sweep vohammetry, cyclic voltammetry and AC impedance methods. The experimental results showed that the cerium ion added in sulfuric acid solution could inhibit the corrosion of the lead-antimony alloy electrode and improve the conductivity of oxide film. The over potential for the oxygen evolution reaction on the electrode was increased, and the corrosion rate was decreased, and moreover the reversibility for the PbSO4/Pb02 transfer reaction was further improved.
