摘要: 本研究分别采用溶剂热法与溶胶–凝胶法，成功制备了Fe3O4磁性纳米材料及具有核壳式结构的Fe3O4/TiO2复合材料。通过调节钛酸四丁酯的用量，实现了对TiO2壳层包覆程度的有效调控。为进一步确定材料性能，采用X射线衍射(XRD)与透射电子显微镜(TEM)对复合材料的微观形貌及结构特性进行了表征与分析。结果表明TiO2壳层为无定型结构，能够避免Fe3O4核的氧化与磁性衰减，拥有便捷磁回收功能。采用煅烧方法将无定型TiO2壳层转变为锐钛矿型。以罗丹明b (RhB)溶液为模拟污染物，在太阳光下进行光催化实验测试材料光催化性能。
Abstract: In this study, Fe3O4 magnetic nanoparticles and Fe3O4/TiO2 magnetic nanocomposites with core-shell structure were successfully prepared by solvothermal method and sol-gel method respectively. The coverage degree of TiO2 shell was effectively regulated by adjusting the amount of tetrabutyl titanate. To further determine the material properties, the microstructure and structural characteristics of the composites were characterized and analyzed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results show that the TiO2 shell is amorphous and effectively avoids the oxidation and magnetic attenuation of the Fe3O4 core, and has a convenient magnetic recovery function. The amorphous TiO2 shell layer was transformed into anatase type by calcination. The photocatalytic performance of the material was tested by designing a photocatalytic experiment under sunlight with Rhodamine b (RhB) solution as a simulated pollutant.
