摘　　要：采用溶胶-凝胶技术将光催化剂H6P2W18O62负载到载体SiO2上,制备了负载型纳米光催化材料H6P2W18O62/SiO2。通过对四种染料的吸附实验,确定了光催化反应的模型分子。研究了该纳米材料对可溶性染料茜素红的光催化活性。结果表明,上述材料在8h的太阳光作用下,对茜素红的脱色率达98%以上。另外,负载后的光催化剂易分离、回收,可循环使用。The photocatalytic nano-material H6P2W18O62/SiO2 was prepared via sol-gel method. The model molecule was selected by the four dyes absorption testing. The photocatalytic activity was studied in this paper. The results indicated that the photocatalytic activity of H6P2W18O62/SiO2 to degrade dye Alizarin S was higher. At the same time, it is easy to separate and recover the composite from the reaction system.
