| 摘要: 采用热分解-电镀法制备了Ti基PbO2阳极(PbO2阳极)和F-掺杂PbO2阳极(F-PbO2阳极)。应用XRD和SEM技术对这两种电极进行了表征，采用加速电解寿命测试研究了其在硫酸溶液中的电解稳定性。结果表明，F-PbO2阳极的寿命远大于PbO2阳极的寿命，在4-氯苯酚(4-CP)的电催化降解过程中，F-PbO2阳极表现出比PbO2阳极较强的催化活性。本文对F-掺杂提高PbO2阳极性能和电催化活性的机理进行了探讨。并应用高效液相色谱确定了4-CP在F-PbO2阳极上的降解历程。 |

| Abstract: Ti-substrate PbO2 and F-doped PbO2 (F-PbO2) anodes were prepared by thermal decomposition-electrodeposition technique. The anodes were characterized by XRD and SEM. The electrochemical stability was studied by the accelerated life tests in H2SO4 solution. The results show that the service life of the F-PbO2 anodes is much more longer than that of the undoped anodes. Moreover， the F-PbO2 anodes show a higher degradation rate for 4-chlorphenol (4-CP) than that observed for the PbO2 anodes. The influence of F- doping on the performance and electrocatalytic activity of PbO2 anodes has been discussed. In addition， the degradation mechanism of 4-CP is proposed according to the results of high-performance liquid chromatograph (HPLC). |
