摘　　要：采用化学氧化法将Keggin结构K8[CdNi(H2O)W11O39]掺杂到聚苯胺中制得K8[CdNi(H2O)W11O39]/PANI掺杂材料,并用UV,IR,XRD,SEM和EDM等测试方法对掺杂材料进行表征.并研究了所合成掺杂材料催化剂为对亚甲基蓝溶液光降解催化活性.通过控制不同的影响条件,寻找光降解的最适条件,实验结果表明:掺杂材料具有很高的催化活性,最适条件下,110min内对亚甲基蓝溶液的脱色率达到99%以上,因此,[CdNi(H2O)W11O39]/PANI掺杂材料是一种很好的光降解催化剂.The doping materials of K8 [CdNi（H2O）W11 O39]/PANI were prepared by the chemical oxi- dation method , and were characterized by UV,IR, XRD, SEM and EDM. The photocatalytic degra- tion acitity of methylene blue solution was studied by doping materials catalyst,under controlling dif- ferent conditions, to find the most suitable conditions of photocatalytic degradation. The experimental results show that doping materials own high catalytic activity, and under the optimum conditions, within 110 min the decolorizing efficiency of the methylene blue solution exceeds 99%, so [CdNi （H2O）W11 O39 ]/PANI is the good photocatalytie degration catalyst.
