摘要(Abstract)：
通过微波水热法合成了ZnFe_2O_4/Ag_3PO_4复合材料,进行了XRD、红外及紫外-可见漫反射表征。并用含10%ZnFe_2O_4的复合材料对50 ppm的罗丹明B(Rhodamine B)、甲基橙(Methyl Orange)、亚甲基蓝(Methylene Blue)染料在模拟太阳光的条件下进行光催化降解。实验结果表明:在降解甲基橙(阴离子型染料) 2 h后降解率仅达20%,降解亚甲基蓝(阳离子型染料) 2 h后降解率达83%,降解罗丹明B (中性分子染料) 2 h后的降解率达到了90%以上,表明这一复合材料是非阴离子型光降解催化剂,对中性染料降解效率大于其它离子型染料;而在5%、10%的复合材料对罗丹明B光催化降解中,10%的复合材料2 h的降解率超过90%,5%的复合材料2 h的降解率接近100%.而且复合材料具有良好的磁性能,有利于回收利用。
