摘要
通过软化学手段制备了一系列新型多金属氧酸盐-有机胺-分子筛(MCM-48)杂化光催化剂K5M(H2O)PW11O39-APS-MCM-48(简写PW11M-APS-MCM-48,M=Co/Ni,APS=(C2H5O)3SiCH2CH2CH2NH2),以六氯苯为探针分子考察了此类杂化光催化剂的催化活性。实验结果表明,此类杂化光催化剂的光催化活性高于直接光解,可有效的降解污水中有机杀虫剂六氯苯。
The polyoxometalate Ks[M(H20)PW11O39] (M = Ni/Co) was supported on amine-functionalized MCM-48 via self-assembly method. and the photocatalytic activity of the hybrid catalysts was studied through photocatalytic degradation of the pesticide hexachlorohenzene. The experimental results indicated that the photocatalytic activity of the hybrid catalysts was higher than those of the direct photolysis Moreover, this kind of catalyst was insoluble in water, and could he reused.
