| 摘 要： | 采用循环伏安法和交流阻抗法研究了碱性水溶液中Pd修饰Ti电极对2-氯酚（2-CP）的电催化还原特性，考察了Pd的沉积时间和甲酸钠对2-CP脱氯效率的影响。研究表明：2-CP在还原过程中属准可逆反应，且由电荷传质与扩散过程混合控制，Pd沉积300s时的催化性能最好，甲酸钠能够促进2-CP的脱氯反应。

| Abstract: | The electrochemical characteristics of the Palladium -modified titanium electrodes towards reduction of 2-chlorophenol （2-CP） in basic solution were investigated by cyclic voltammetry and AC impedance. The experiments were carried out to explore the effects of palladium loading and sodium formate addictive on the dechlorination of 2-CP. It was found that the electroreduction reaction of 2-chlorophenol was irreversible and the reaction process was controlled by mass transfer of charge/diffusion in solution. The palladium deposition time was 300 s and the electrodes had the best powerful electrocatalytic activity for the reduction of 2-CP. The sodium formate can enhance the dechlorination of 2-CP. |
