We report a facile method to synthesize dispersed Fe3O4@C nanoparticles (NPs). Fe3O4 NPs were firstly prepared via the high temperature diol thermal decomposition method. Fe3O4@C NPs were fabricated using glucose as a carbon source by hydrothermal process. The obtained products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM) and Raman spectra. The results indicate that the original shapes and magnetic property of Fe3O4 NPs can be well preserved. The magnetic particles are well dispersed in the carbon matrix. This strategy would provide an efficient approach for existing applications in Li-ion batteries and drug delivery. Meanwhile, it offers the raw materials to assemble future functional nanometer and micrometer superstructures.
