摘要
文章采用阳极氧化法制备了TiO2纳米管电极、TiO2膜电极,对其进行了SEM、XRD表征的比较。研究了电化学过程、光解、TiO2纳米管的光催化、TiO2纳米管电极的光电催化对五氯苯酚的降解,研究表明光电催化降解速度最快。此外,TiO2纳米管电极和TiO2膜电极对五氯苯酚的光电催化降解也进行了研究。结果表明,TiO2纳米管电极对五氯苯酚光电催化效果明显好于TiO2膜电极,2h二者的降解率分别为81.5%,69%。
TiO2 nanotube electrode and TiO2 film electrode were both fabricated by anodic oxidation in the study. They were characterized by scanning electron microscope （SEM）andX-ray diffraction （XRD）. The electrochemical, photolytic, photocatalytic, and photoelectrocatalytic degradation of pentachlorophenol on TiO2 nanotube electrode were investigated in the study. The results indicated that the efficiency of photoelectrocatalytic degradation was the best in these four processes. In addition, the photoelectrocatalytic degradation of pentachlorophenol on TiO2 nanotube electrode and TiO2 film electrode were also studied. TiO2 nanotube electrode exhibited increased photoelectrocatalytic （PEC） capability compared to TiO2 film electrode. The degradation efficiency on TiO2 nanotube electrode and TiO2 film electrode for 2 hrs were 81.5 % and 69 %, respectively.
