Abstract: The β-PbO2/TiO2 nanotubes(β-PbO2/TiO2-NTs) electrode was prepared using the anodic oxidation method and pulsed electrochemical deposition(PED). The properties of β-PbO2/TiO2-NTs 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/TiO2-NTs electrode had high electrocatalytic activities and the COD removal rate of phenol reached up to 83%.
