以电化学方法制备了Ti/TiO2-NTs、Ti/TiO2-NTs/Ag2O、Ti/TiO2-NTs/Ag2O/PbO2电极,用TEM、SEM、XRD等方法表征了3种电极表面的形貌。以Ti/TiO2-NTs/Ag2O/PbO2电极作阳极,对100 mg/L的PFOA溶液进行降解。结果表明:在电流密度为30 mA/cm2下降解180 min后,PFOA去除率可达99.47%,脱氟率高达87.53%,具有较高的电氧化能力。

Electrodes,including Ti/TiO_2-NTs,Ti/TiO_2-NTs/Ag_2O and Ti/TiO_2-NTs/Ag_2O/PbO_2,have been prepared by electrochemical methods,and the surface shapes of the three kinds of electrodes characterized by TEM,SEM and XRD,etc. Ti/TiO_2-NTs/Ag_2O/PbO_2 electrode as anodic electrode has been used for the degradation of 100 mg/L of PFOA solution. The results show that PFOA removing rate can reach 99.47% and the defluorination rate is as high as 87.53% when current density is 30 mA/cm~2,and degradation time...
