摘　　要：采用沉淀法制备出了ZnFe_2O_4及Zn O/ZnFe_2O_4复合材料。利用X衍射仪(XRD)及扫描电镜(SEM)对其结构和形貌进行表征。实验结果表明,通过XRD可知制备出ZnFe_2O_4及ZnO/ZnFe_2O_4样品;通过SEM可知ZnFe_2O_4为不规则的颗粒状,ZnO/ZnFe_2O_4为球型且附着有细小颗粒。在模拟太阳光(氙灯)下用0.2 g ZnO/ZnFe_2O_4对100 mL模拟有机废水(20 mg/L的亚甲基蓝)进行实验,降解效率可达89.2%。In this paper, ZnFe2O4 and ZnO/ZnFe2O4 were synthesized by precipitation method. The structure and appearance of the synthesized nanopartieles were characterized by XRD and SEM. The results show that ZnFe2O4 and ZnO/ZnFe2O4 can be successfully prepared by XRD; we can find that the ZnFe2O4 is irregular, and the ZnO/ZnFe2O4 is the ball type and the small particles are attached. A study on the photocatalytie performance of the simulated wastewater （ Methylene blue） with ZnO/ZnFe2O4 under the simulated sun]ight showed that the highest degradation rate could reach to 89.2%.
