采用水热法以钛酸四丁酯为前躯物制备了CNTs/Fe3O4/TiO2纳米复合材料,利用x射线衍射仪(XRD)和透射电镜(TEM)分析了样品的微观结构和形貌,结果表明实验成功在CNTs/Fe3O4表面负载了锐钛矿型TiO2;样品在水中有良好的分散性和磁场可控性。
CNTs / Fe3O4 / TiO2 nanocomposites were prepared by hydrothermal method using tetrabutyl titanate as precursor. The microstructure and morphology of CNTs / Fe3O4 / TiO2 nanocomposites were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) The experimental results show that anatase TiO2 is loaded on the CNTs / Fe3O4 surface. The sample has good dispersibility in water and controllability of magnetic field.
