| 摘 要： | 通过自组装技术制备了一系列多金属氧酸盐-有机胺-分子筛杂化催化剂K5［M(H2O)PW11O39］-(EtO)3Si(CH2)3NH2-MCM-48,用XRD,ICP-AES,UV/DRS,FT-IR,31P MAS NMR和N2吸附等手段对其组成和结构进行了表征,并以有机杀虫剂六氯苯为探针分子考察了其光催化活性. 结果表明,多金属氧酸盐杂化催化剂的光催化降解活性高于直接光解,能有效地降解污水中的六氯苯,且易分离,可循环使用.

| Abstract: | The polyoxometalate (POM) K 5 M(H 2O)PW 11 O 39 ] (M=Co, Ni) was supported on amine-functionalized MCM-48 via self-assembly method. The XRD, UV/DRS, FT-IR, ICP-AES, 31 P MAS NMR, N 2 adsorption and elemental analysis were used to characterize the structure of the hybrid catalysts, and the photocatalytic activity of the catalysts was measured through the degradation of hexachlorobenzene. The results indicated that the photocatalytic activity of the catalysts was higher than that of the direct photolysis. Moreover, this kind of catalysts was insoluble in water, and could be reused. |
