| 摘 要： | 结合电泳法和电沉积法制备了含碳纳米管(CNT)夹层的PbO_2电极(CNT-PbO_2),扫描电子显微镜图像表明,在CNT夹层表面电沉积10minβ-PbO_2活性层可获得β-PbO_2晶粒较多、晶粒尺寸较小、比表面积较大的CNT-PbO_2电极。利用CNT-PbO_2电极电催化氧化降解水中苯胺,研究电流密度、苯胺初始浓度、温度、支持电解质浓度对苯胺降解率的影响。实验结果表明:随着电流密度的增加,苯胺的降解率升高;苯胺初始浓度越高,苯胺的降解率越低;在实验范围内,温度和支持电解质浓度对电催化氧化降解苯胺过程影响较小。

| Abstract: | In this study,the PbO2 electrode with carbon nanotube (CNT) is prepared by electrophoresis and electric deposition. The images from the scanning electron microscopy show that the PbO2 electrode with large specific surface area of CNT containing many small Beta PbO2 grains can be obtained in the 10 min beta PbO2 electrodeposed active layer on the surface of CNT. The CNT PbO2 electrode is applied to electrocatalyse, oxidize and degrade aniline in water so as to study the effect of current density, aniline initial concentration, temperature, electrolyte concentration on the degradation rate of aniline. The results show that the aniline degradation ratio increases with the rise of applied current density,that the greater the aniline initial concentration is,the lower the aniline degradation ratio is and that in the experimental range, the temperature and the concentration of the supporting electrolyte has little influence on the electrocatalytic oxidation and degradation of aniline. |
