摘　　要：采用静电自组装法制备了复合材料K_8[Cu(H_2O)ZnW_(11)O_(39)]/PANI/ZrO_2,并采用IR、UV、XRD、N_2吸附-脱附、SEM、XPS、TG的检测手段对其进行了表征,且以制备的K_8[Cu(H_2O)ZnW_(11)O_(39)]/PANI/ZrO_2为催化剂,考察了K_8[Cu(H_2O)ZnW_(11)O_(39)]/PANI/ZrO_2的光催化活性,以二甲酚橙为模型,在紫外光照射条件下,确定最佳光催化条件为:二甲酚橙溶液的初始浓度为5 mg·L^(-1),二甲酚橙溶液的初始pH值为4,K_8[Cu(H_2O)ZnW_(11)O_(39)]/PANI/ZrO_2的用量为0.0200 g。最佳条件下,二甲酚橙溶液的脱色率可达93.72%。The composite material of K8[Cu（ H2O）ZnW11O39]/PANI/ZrO2 was synthesized by electrostatic self-assembly method,and was characterized by IR、UV、XRD、N2 adsorption-desorption、SEM、XPS and TG,the photocatalytic activity of K8[Cu（H2O）ZnW11O39]/PANI/ZrO2 were studied for photocatalytic degradation of xylenol orange as a model under the condition of UV irradiation,and the optimum experimental reaction conditions of photocatalytic degradation were determined.The results indicated that the initial concentration of xylenol orange solution was 5 mg·L^-1,the initial pH of xylenol orange solution was 4,the quantity of K8[Cu（H2O）ZnW11O39]/PANI/Zr O2 was 0. 0200 g,the decolorizing rate reached 93. 72% under the best conditions.
