| 摘 要： | 以邻苯二甲酸二乙酯(DEP)为模板分子,在TiO2纳米管阵列(TNA)上沉积了能识别DEP分子的TiO2纳米颗粒,制备了DEP分子印迹型TNA(DM-TNA)。X射线衍射(XRD)测试表明,DM-TNA的晶体结构是锐钛矿。扫描电镜(SEM)测试显示颗粒大小约为20 nm的TiO2纳米颗粒均匀地涂覆在TNA的管壁上。光电催化降解DEP和2,4-二氯苯酚(DCP)的结果表明,DM-TNA降解DEP的活性高于非分子印迹TNA(NM-TNA),而DM-TNA降解DCP的活性低于NM-TNA。DM-TNA降解DEP的速率常数是NM-TNA的2.76倍。

| Abstract: | Using diethyl phthalate (DEP) as template, molecularly imprinted TiO2 nanoparticles were deposited on wall of TNA and DEP-molecularly-imprinted TNA (DM-TNA) was fabricated. X-ray diffraction (XRD) analysis demonstrated that crystal structure of DM-TNA was anatase. Scanning electron microscopy (SEM) measurements showed that TiO2 nanoparticles with a size about 20 nm were uniformly coated on the wall of TNA. The results of photoelectrocatalytic degradation of the mixed solution of DEP and 2,4-dichlorophenol (DCP) showed that the degradation activity of DEP on the DM-TNA was higher than that on non molecularly imprinted TNA (NM-TNA), while the degradation activity of DCP on the DM-TNA was lower than that on NM-TNA. The rate constant of DM-TNA for the degradation of DEP was 2.76 times that of NM-TNA. |
