AB  - In this study, we fabricated a blue-TiO(2)/PbO(2)-carbon nanotube (CNT) electrode 
      in which blue TiO(2) nanotube arrays (blue-TNA) served as the substrate for 
      PbO(2)-CNT eletrodeposition. Scanning electron microscope (SEM) showed compact 
      surface structure of the electrode. The beta-PbO(2) crystal structure was detected 
      by X-ray diffraction (XRD). The distribution of Pb, O, C, and Na elements on the 
      electrode surface have been confirmed by X-ray photoelectron spectroscopy (XPS). 
      Blue-TiO(2)/PbO(2)-CNT electrode had higher response current (213.12 mA), larger 
      active surface area and lower charge transfer resistance (2.22 Omega/cm(2)) than 
      conventional TiO(2)/PbO(2)-CNT electrode. The influences of current density, 
      initial phenol concentration, initial solution pH, and Na(2)SO(4) concentration 
      on the electrochemical oxidation of phenol have been analyzed. The results showed 
      that the 100 mg/L phenol could be destroyed completely after 210 min, and 
      chemical oxygen demand (COD) removal rate was 89.3% within 240 min. Additionally, 
      the electrode showed long actual lifetime (5468.80 hr) and low energy consumption 
      (0.08 kWh/gCOD). A phenol degradation mechanism was proposed by analyzing the 
      intermediate products with high-performance liquid chromatography-mass 
      spectrometry (HPLC-MS). Importantly, the blue-TiO(2)/PbO(2)-CNT electrode 
      exhibited superior stability and high degradation efficiency after 15 times 
      reuse, demonstrating its promising application potential on phenol-containing 
      wastewater treatment.
