摘　　要：制备了α-SiW_(11)Fe/PANI/ZnO三元复合催化剂,并用红外光谱、紫外光谱、XRD、SEM进行表征。并以模拟污染物刚果红为光催化降解探针来评价α-SiW_(11)Fe/PANI/ZnO的光催化活性。结果表明:α-Si W_(11)Fe/PANI/Zn O在紫外灯照射下降解100 m L刚果红的最佳条件为:p H=5,刚果红初始质量浓度15 mg/L,催化剂用量40 mg/L,脱色率可达91.88%。光催化降解刚果红符合准一级动力学模型。The ternary composite catalystα-SiW11Fe/PANI/ZnO was prepared,and then characterized by IR,UV,XRD and SEM.The photocatalytic degradation of congo red was selected as probe to evaluate the photocatalytic activity ofα-SiW11Fe/PANI/ZnO.The results showed that the optimum conditions for the degradation of 100 mL congo red under UV light were as follows:pH=5,initial content of congo red 15 mg/L,catalyst dosage 40 mg/L.Under these conditions,the decoloration of congo red achieved 91.88%.The photocatalytic degradation of congo red withα-SiW11Fe/PANI/ZnO followed the characteristic first-order reaction kinetics.
