  • 摘要: 采用电沉积法制备了Fe掺杂PTFE-PbO2/TiO2-NTs/Ti、PbO2/TiO2-NTs/Ti、PbO2/Ti 3种电极,运用扫描电镜、X射线衍射仪观察表面形貌与形态,通过线性扫描伏安法在0.1 mol·L-1的H2SO4中测定电极的析氧极化曲线.以对硝基酚(p-NP)为目标污染物,考察了电极的电催化活性,在20 mA·cm-2电流密度下降解100 mg·L-1 p-NP,120 min时表观速率常数分别为0.0370 min-1、0.0265 min-1和0.0180 min-1,COD去除率分别为77.38%、74.07%、66.18%,研究发现在相同的条件下Fe掺杂PTFE-PbO2/TiO2-NTs/Ti性能更佳,矿化更完全.
    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稬-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稬-1 concentration was treated under the current density of 20 mA穋m-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.
