摘要: 以石墨毡为电极材料, 以甲基磺酸和甲基磺酸铅溶液为电解液组成全沉积型铅酸液流电池体系, 研究了PbO2/Pb(II)电对在石墨毡电极上的电化学反应动力学特征和电极表面改性处理对PbO2/Pb(II)电对反应动力学行为的影响。结果表明: 实验测得的PbO2/Pb(II)电对在石墨毡电极上的平衡电极电位值为1.25 V, 与理论值接近, 且电极反应在平衡状态下的动力学特性较好;循环伏安曲线的氧化峰与还原峰电位分别为1.54 V和1.238 V, 表明石墨毡电极Pb(II)与PbO2之间的还原反应比氧化反应更容易;在浓酸、热、热与酸结合三种表面改性方法中, 以浓甲基磺酸处理的石墨毡表面电化学活性最好。

Abstract:The chemistry system with graphite felt electrode and a single electrolyte, lead(II) in methanesulfonic acid was described in this paper. The effects of treatment methods on kinetics and cyclic voltammetry behavior of PbO2/Pb(II) couple were investigated. The results show that the equilibrium electrode potential PbO2/Pb(II) couple is 1.25 V and the PbO2/Pb(II) couple on graphite felt electrode has a good kinetics behavior. The cyclic voltammetry behavior of PbO2/Pb(II) couple on graphite felt electrode was investigated, and the oxidization and reduction peak potentials are 1.54V and 1.238V, respectively. The graphite felt treated with methanesulfonic acid, heat and both showed good electrocatalytic activity for PbO2/Pb(II) couple, and the treatment method with methanesulfonic acid is best.
