Synthesis and Characterization of the Graphene-Fe3O4 Hybrid Composite.

Graphene and iron oxide composites have attracted huge attention in the fields of nanoelectronics and nanodevices due to their superior magnetic and electric characteristics. However, their synthesis methods are composed of many steps and use toxic chemical reactants. Accordingly, in this study, a GN-Fe3O4 NP hybrid composite was prepared using an eco-friendly and facile method. Its morphological and structural characteristics were then investigated by scanning electron microscopy, transmission electron microscopy, X-ray diffractometer and UV-visible spectroscopy. The results indicated that the GN structures as well as Fe3O4 NPs were significantly associated with the composite of GN-Fe3O4 NPs.
