| 摘 要： | 以胺修饰的中孔氧化硅为载体，通过自组装技术制备了一取代keggin结构的K5［Ni（H2O）PW11O39］(以下简称PW11Ni)复合材料，并研究了该复合材料对可溶性染料罗丹明B(简称RB)光催化的活性。实验结果表明。该复合材料光催化RB的活性高于RB的直接光解和PW11Ni均相光催化。其中，复合材料PW11Ni—APS—SiO2可在180min内使RB的转化率达到91．6％。具有一定的开发价值。

| Abstract: | With amine-functionalized mesoporous silica materials as the support, The composites of polyoxometalate K5Ni(H2O)PW11O39] (PW11Ni) were prepared via self-assembly method. The photocatalytic activities of the composites were studied through photocatalytic degradation of dye Rhodamine B (RB). The results show that the photocatalytic activity, of the composite PW11Ni-APS-SiO2 was higher than that of the composite PW11Ni-APS-SIO-7.Moreover, the composites can remain high catalytic activities after reuse of many times. |
