【摘要】 通过微波水热法合成了ZnFe₂O₄/Ag₃PO₄复合材料,进行了XRD、红外及紫外-可见漫反射表征。并用含10%ZnFe₂O₄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。更多还原

【Abstract】 ZnFe₂O₄/Ag₃PO₄ composite was synthesized by microwave hydrothermal method. With composite material containing 10% ZnFe₂O₄ to 50 PPM of Rhodamine B（ Rhodamine B）,Methyl Orange（ Methyl Orange） and Methylene Blue（ Methylene Blue） dye in simulated sunlight under the conditions of photocatalytic degradation,the experimental results show that the degradation of methyl orange（ anionic dyes） 2 h after the degradation rate was20%,and the only degradation of methylene blue（ cationic dye） 2 h after the degradation rate was 83%,and the degradation of rhodamine B（ neutral dye molecules） 2 h after degradation rate reached more than 90%,which show that this composite material are anionic photodegradation catalysts,the neutral dye degradation efficiency than other ionic dyes; In the photocatalytic degradation of rhodamine B by 5% and 10% of the composites,the degradation rate of 10% of the composites was more than 90% at 2 h,and the degradation rate of 5% of the composites was close to 100% at 2 h. And the composite material has good magnetic properties,which is conducive to recycling.更多还原
