摘要 参考文献 相关文章 Metrics 全文: PDF(884 KB)   摘要: 用电沉积法制备表面活性剂聚乙二醇(PEG)和溴化十六烷基吡啶(CPB)复配改性PbO2电极, 用SEM、XRD、电化学阻抗谱(EIS)和线性极化扫描(VA)等方法对其微结构和电化学性能进行了表征。结果表明, PEG/CPB复配改性在改善PbO2镀层微结构中产生协同增效作用, 使电极表面颗粒进一步细化均匀; 复配改性电极明显提升了苯酚的催化降解活性, 在2.5 h内对100 mg•L-1苯酚溶液的降解率为98.7%。PEG/CPB复配改性电极电催化活性的提升与电极的活性表面积增大、电化学反应电阻减小和析氧电位的提高有关。 关键词 ： 无机非金属材料,  二氧化铅电极,  表面活性剂,  复配改性,  电催化     Abstract：PbO2 electrode modified with a mixture of polyethylene glycol (PEG, non-ionic surfactant) and cetylpyridinium bromide(CPB, cationic surfactant) was prepared by electrodeposition method. The micro-structure and electrochemical properties of the modified electrode were investigated by SEM, XRD, electrochemical impedance spectroscopy (EIS) and liner sweep voltammetry(VA) techniques. Results show that PEG and CPB display synergistic effect in improving the micro-structure of PbO2 coating which refine the crystalline grains of electrode. The combined modification of PEG and CPB can enhance the electro-catalytic activity of PbO2 electrode for phenol degradation, and 98.7% degradation ratio of phenol with an initial concentration of 100 mg·L−1 can be obtained at 2.5 h. The modified electrode has larger active surface area, lower charge-transfer resistance and higher oxygen evolution potential, and these characteristics promote the electro-catalytic activity of the PbO2 electrode for decomposition of organic matter.
