| Abstract: | A new and relatively general route was developed to fabricate graphene oxide (GO)-Fe3O4 hybrid. X-ray diffraction, transmission electron morphology, X-ray photoelectron spectroscopy (XPS) and energy-dispersive spectrum were used to demonstrate the successful attachment of iron oxide nanoparticles to GO sheets. Transmission electron microscopy observation indicates that the size of the Fe3O4 nanoparticles was about 2.7 nm with narrow size distribution. Moreover, this hybrid shows superparamagnetic property and allows the rapid separation under an external-magnetic field. In addition, the method could be extended to further development of graphene-based nanoelectronics. |
