| Abstract: | Fe-doped PTFE-PbO2/TiO2-NTs/Ti,PbO2/TiO2-NTs/Ti and PbO2/Ti were prepared by anodic electrodeposition technique.The microstructure and morphology were analyzed by scanning electron microscope(SEM) and X-ray diffraction(XRD).Polarization curves of oxygen evolution of the three electrodes were studied by linear sweep voltammetry in 0.1 mol·L-1 H2SO4 aqueous solution.The electro-catalysis of the fabricated electrodes was also investigated using p-nitrophenol(p-NP) as a model pollutant.p-Nitrophenol with 100 mg·L-1 concentration was treated under the current density of 20 mA·cm-2 for 120 min.The apparent rate constant was 0.0370 min-1,0.0265 min-1and 0.0180 min-1,COD removal efficiency was 77.38%,74.07% and 66.18%,respectively.Compared with the other two electrodes,the Fe-doped PTFE-PbO2/TiO2-NTs/Ti had a better performance and the mineralization was greater. |
