摘要: 采用阳极氧化法和脉冲电沉积制备出β-PbO₂改性TiO₂纳米管(β-PbO₂/TiO₂-NTs)电极,通过扫描电子显微镜(SEM)、X射线衍射(XRD)和X射线光电子能谱(XPS)等技术手段对制备的β-PbO₂/TiO₂-NTs电极的表面形貌和结构进行了表征。结果表明,该方法成功地将β-PbO₂纳米颗粒分散在TiO₂纳米管中,通过电催化降解苯酚评价了β-PbO₂/TiO₂-NTs电极的电催化活性,实验结果表明,在TiO₂-NTs中电沉积β-PbO₂提高了电极的电催化活性,对苯酚的降解达到83%。

Abstract: The β-PbO₂/TiO₂ nanotubes(β-PbO₂/TiO₂NTs) electrode was prepared using the anodic oxidation method and pulsed electrochemical deposition(PED). The properties of β-PbO₂/TiO₂NTs electrode were characterized by scanning electron microscopy(SEM), X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS). The results indicate that β-PbO₂ nanoparticles are successfully dispersed inside the TiO₂ nanotubes. The degradation of phenol was carried out to test the electrocatalytic performance of the β-PbO₂/TiO₂ NTs electrode, which indicated that the β-PbO₂/TiO₂NTs electrode had high electrocatalytic activities and the COD removal rate of phenol reached up to 83%.
