摘要
以自制的氧化石墨烯、BiOCl/Fe_3O_4为原料,以水合肼为还原剂,制备出Fe_3O_4/石墨烯(G)-BiOCl复合光催化剂。运用X射线衍射、透射电镜和扫描电镜对Fe_3O_4/G-BiOCl的组成和形貌进行了表征,运用振动样品磁强计对其磁性进行了测试;对照研究了Fe_3O_4/G-BiOCl、BiOCl/Fe_3O_4和纯BiOCl对罗丹明B的光催化降解能力以及Fe_3O_4/G-BiOCl光催化活性的循环稳定性。结果表明:Fe_3O_4/G-BiOCl复合光催化剂分布均匀,具有超顺磁性;Fe_3O_4/G-BiOCl的光催化性能优于纯BiOCl和BiOCl/Fe_3O_4,可回收再利用,并具有良好的循环稳定性。
Fe3O4/G-BiOCl nanocomposites were prepared by an ultrasonic Hummers method with monolayer graphene oxides,BiOCl nanosheets and superparamagnetic Fe3O4 nanoparticles as raw materials.The properties of Fe3O4/GBiOCl nanocomposites were then characterized by XRD,TEM,SEM and VSM.The results showed that the nanocomposites exhibited an excellent photocatalytic property and cycle stability,which was much better than pure BiOCl and BiOCl/Fe3O4 nanocomposites.
