摘要

采用热分解-电镀法制备了聚四氟乙烯（PTFE）掺杂PbO2电极（Ti/PTFE-PbO2）和PTFE、CeO2共掺杂PbO2电极（Ti/CeO2-PTFE-PbO2），考察了电流密度、温度、搅拌速率、CeO2浓度等工艺条件对电极寿命的影响。对Ti/CeO2-PTFE-PbO2的电催化氧化性能进行了初步研究。结果表明，在电流密度为30 mA·cm-2、温度80℃、搅拌速率为1300 r·min-1和CeO2为3 g·L-1等较优条件下，Ti/CeO2-PTFE-PbO2电极在9 mol·L-1 H2SO4溶液中的强化电解寿命（1A·cm-2）达983 h。SEM和EDX的分析结果表明，PTFE、CeO2共掺杂使得Ti/CeO2-PTFE-PbO2表面的晶粒排布更均匀致密，电解过程镀层的铅氧计量比也具有较高的稳定性。由于具有更高的析氧电位，与Ti/PTFE-PbO2电极相比，Ti/CeO2-PTFE-PbO2电极对对氯苯酚的降解显示了更好的电催化活性。

Abstract

Ti substrate polytetrafluoroethylene（PTFE）-doped PbO2（Ti/PTFE-PbO2）and PTFE，CeO2-codoped PbO2（Ti/CeO2-PTFE-PbO2）electrodes were prepared by a thermal decomposition-electrodeposition technique，and the factors affecting the electrode lifetime，like current density，temperature，stirring speed and CeO2 concentration were investigated as well.The electro-oxidative performance of Ti/CeO2-PTFE-PbO2 was investigated.The results showed that the prepared Ti/CeO2-PTFE-PbO2 electrode had a long accelerated electrolysis lifetime（about 983 h）under the optimum plating conditions，like current density 30 mA·cm-2，temperature 80℃，stirring speed 1300 r·min-1 and CeO2 concentration 3 g·L-1.The results of SEM and EDX analysis indicated that the Ti/CeO2-PTFE-PbO2 electrode had a denser structure and better stability of nonstoichiometry than common PbO2 electrode had during the accelerated electrolysis.Compared with Ti/PTFE-PbO2 anode，Ti/CeO2-PTFE-PbO2 anode had a higher electro-catalytic activity for the degradation of 4-CP because of its higher potential for oxygen evolution.
