摘要/Abstract

摘要： 在钛板上制备了氧化铈掺杂的含氟二氧化铅电极(Ti/CeO2-F-PbO2,电沉积法).SEM和XRD分析显示CeO2颗粒能均匀地嵌入二氧化铅镀层中.电化学测试表明,掺杂CeO2提高了二氧化铅的析氧电位(Ti/CeO2-F-PbO2为1.83V,vs.SCE,Ti/F-PbO2为1.78V,vs.SCE).对氯苯酚降解结果表明,Ti/CeO2-F-PbO2电极有较高的COD去除率和电流效率.

关键词: 二氧化铅, 掺杂, CeO2, 降解, 对氯苯酚

Abstract: The CeO2-modified PbO2 on Ti plate ( Ti/CeO2-F-PbO2) was prepared by electrodeposition. The SEM and XRD analyses indicated that the CeO2 particle could be beuniformly co-deposited in the film of PbO2. The results of electrochemical test showed that the Ti/CeO2-F-PbO2 anode had higher potential ( 1. 83 V. vs. SCE) for oxygen evolution ( OE) than the Ti/F-PbO2 anode ( 1. 78 V,vs. SCE) . The degradation of 4-chlorophenol was carried out to test electrocatalytic performance of this novel electrode,which indicated that Ti/CeO2-F-PbO2 anode had high COD removal rate and instantaneous current efficiencies ( ICE) .

Key words: PbO2, doped, CeO2, degradation, 4-chlorophenol
