摘　　要：本文通过Hummer法制备了氧化石墨烯(GO),通过水热法制备了磁性氧化石墨(MGO)和磁性氧化石墨烯/MIL-100(Fe)(MGO/MIL-100(Fe)0.3)复合材料,并用扫描电镜、透射电镜、红外光谱、X射线衍射和热重分析对样品进行了表征。研究了磁性氧化石墨烯复合材料和磁性氧化石墨烯/MIL-100(Fe)复合材料在可见光和紫外光下,光催化降解吖啶橙染料废水。实验结果表明,在紫外光的照射下,MGO/MIL-100(Fe)0.3与MGO相比催化性能有明显提高,且磁性氧化石墨/MIL-100(Fe)复合材料可重复使用4次,其作为处理印染废水的光催化剂具有潜在的应用价值。Graphene oxide(GO)was prepared by Hummer method,then magnetic graphene oxide composite(MGO)and MGO/MIL-100(Fe)0.3 composites were prepared by hydrothermal method.The samples were characterized by scanning electron microscopy (SEM),transmission electron microscopy(TEM),fourier infrared spectra(FTIR),X-ray diffraction spectra(XRD)and thermogravimetric analysis(TG).The photocatalytic properties of MGO and MGO/MIL-100(Fe)0.3 composite for acridine orange under visible and ultraviolet light were studied.The experimental results show that MGO/MIL-100(Fe)0.3 has better catalytic performance than MGO under UV irradiation,and MGO/MIL-100(Fe)0.3 can be reused for four times,which has potential application value as a photocatalyst for the treatment of printing and dyeing wastewater.
