SYNTHESIS AND CHARACTERIZATION OF Fe3O4@C@γ-Al2O3 CORE@DOUBLE-SHELL NANOCOMPOSITE

An efficient magnetic carbon nanospheres supported γ-Al2O3 as a core@double-shell nanocomposite has been prepared by a three-step process in this report. The morphology, inner structure and magnetic properties of all products were studied with X-ray powder diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), field-emission scanning electron microscopy (FE-SEM) and vibrating sample magnetometer (VSM) tests. The Fe3O4@C@γ-Al2O3 nanocomposite showed excellent particle monodispersity and uniform particle diameter of 100-300 nm. The synthesized nanocomposite showed great magnetic property (52.3 emu/g), which made it has potential for application in magnetic nanodevices and nanocatalysts.
