Reduced Graphene Oxide/Magnetite Nanocomposites: Synthesis and Characterization

In this paper, an efficient method for the synthesis of Reduced Graphene Oxide/Magnetite RGO/Fe3O4 nanocomposite is presented. The properties of RGO/Fe3O4 nanocomposite were investigated using FT-IR, XRD, VSM and SEM. The average size of Fe3O4 nanoparticles on graphene substrates was obtained 22 ± 5 nm using SEM images. The VSM results demonstrate that there is no apparent change in the properties of magnetite nanoparticles in RGO/Fe3O4 nanocomposite. Therefore, this nanocomposite could be appropriate for magnetic applications. In cyclic voltammetry studies, oxidation current enhancement was observed when magnetite nanoparticles loaded on graphene substrates, which could make RGO/Fe3O4 nanocomposite as an efficient electrochemical sensor.
