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。

关 键 词:电催化    F-PbO2阳极    降解    4-氯苯酚

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).
Keywords:electrocatalysis  F-PbO2 anodes  degradation  4-chlorphenol
