摘要
以活性炭(AC)作为载体,采用简易的低温液相法制备了3种不同负载比例的ZnO/AC复合光催化材料,利用XRD、SEM及FT-IR对产物进行了表征分析,并对亚甲基蓝(MB)进行了光催化性能测试。结果表明,AC表面负载的ZnO属于纤锌矿结构,具有良好的结晶度,粒径较小。与纯ZnO和AC相比,ZnO/AC复合光催化剂对MB显示了增强的光催化活性。同时,ZnO的负载比例对复合光催化剂的光催化效果具有显著影响,可多次循环使用而不失活。
Three ZnO/AC composite photocatalytic materials with different load proportion were prepared by a facile low-temperature liquid phase method using actived carbon（AC）as the carrier.The products were characterized by XRD,SEM,FT-IR,and their phototalytic activity was tested by methylene blue（MB）.The results showed that ZnO with wurtzite structure loaded on AC surface had good crystallinity,and its particle size was small.Compared with the pure ZnO and AC,ZnO/AC composite photocatalyst showed the enhanced photocatalytic activity for MB.In addition,load ratio of ZnO showed a significant effect on photocatalytic effect of photocatalyst and it can be reused many times without inactivation.
