采用阳极氧化法制备了二氧化钛（TiO2）纳米管薄膜电极。扫描电子显微镜（SEM）显示，这些管排列良好，并组织成高密度的均匀阵列。XRD分析表明，TiO2纳米管为单晶结构。与传统的阳极氧化法制备的TiO2膜电极相比，TiO2纳米管膜电极对五氯苯酚（PCP）的光电催化降解能力有所提高。结果表明，偏压、pH值和电解质浓度是影响以TiO2纳米管膜电极为工作电极的PEC法降解PCP的重要因素。(C)2006爱思唯尔有限公司版权所有。
Titanium dioxide (TiO2) nanotube film electrodes are fabricated by the anodic oxidation method. Scanning electron microscopy (SEM) showed that these tubes were well aligned and organized into high-density uniform arrays. XRD analysis showed the TiO2 nanotubes to be in the anatase crystal form. The TiO2 nanotube film electrode exhibited increased photoelectrocatalytic (PEC) capability compared to a traditional TiO2 film electrode fabricated using the anodizing method for pentachlorophenol (PCP) degradation in aqueous solution. The bias potential, pH value, and electrolyte concentration were shown to be important factors influencing the degradation of PCP by the PEC method using the TiO2 nanotube film electrode as the working electrode.
