We report a facile method to synthesize dispersed Fe_3O_4@C nanoparticles(NPs). Fe_3O_4 NPs were firstly prepared via the high temperature diol thermal decomposition method. Fe_3O_4@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 Fe_3O_4 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.
