【 摘 要 】

Magnetic nanomaterials with emergent physical and chemical properties have paid much attention, however, their synthesis pathways are still a challenge. In this study, we described a simple method for the synthesis of graphene oxide-decorated magnetic nanoparticles GO@MFe2O4 (M = cobalt, manganese and nickel metal sites) from ferrites MFe2O4 via complex polymerization method and graphene oxide via Hummer's method. The structure of GO@MFe2O4 were characterized by several physicochemical techniques, such as X-ray Diffraction (XRD) and Scanning electron microscope (SEM), Brunauer-Emmett-Teller (BET), point of zero charge (pHpzc) and Fourier-transform infrared spectroscopy (FTIR). The results indicated a spinel-like structure of GO@MFe2O4 with high porosity and surface area, along with strong saturation magnetization, which can become a potential candidate for various applications.
