Abstract

The photocatalytic activity efficiency of TiO2 for the degradation of Toluene in photoreactor can be enhanced by nanoTiO2/LDPE composite film. Since the amount of TiO2 affected the efficiency of the photocatalytic activity, this work was mainly concentrated on the effort to embed the high amount of TiO2 in the Polyethylene matrix. The developed photocatalyst was characterized by XRD, UV-Vis spectrophotometer and SEM. The SEM images revealed the high homogeneity of the deposition of TiO2 on the polyethylene matrix. The XRD patterns interpreted that TiO2 embedded in the PE matrix exhibited mainly in anatase form. In addition, the photocatalytic results show that the toluene removal efficiencies of 30±5%, 49±4%, 68±5%, 42±6% and 33±5% were obtained when using the catalyst loading at 0%, 10%, 15%, 25% and 50% (wt. cat./wt. film), respectively. Keywords—Photocatalytic oxidation, Toluene, nano-TiO2/LDPE composite film.

纳米tio2 /LDPE复合膜光催化氧化降解挥发性有机化合物

纳米TiO2/LDPE复合膜可提高TiO2在光反应器中降解甲苯的光催化活性。由于TiO2的含量会影响光催化活性的效率，因此本工作主要集中在将大量TiO2嵌入聚乙烯基体上。采用XRD、UV-Vis分光光度计和SEM对所制备的光催化剂进行了表征。SEM图像显示TiO2在聚乙烯基体上的沉积具有较高的均匀性。XRD分析表明，TiO2主要以锐钛矿形式包埋在PE基体中。此外，光催化结果表明，当催化剂负载为0%、10%、15%、25%和50% (wt. cat./wt.)时，甲苯去除率分别为30±5%、49±4%、68±5%、42±6%和33±5%。电影),分别。关键词:光催化氧化，甲苯，纳米tio2 /LDPE复合膜
