Synthesis and characterization of magnetic graphene oxide as a solid support for metal nanoparticles

Graphene oxide, a derivative of graphene, due to many exceptional properties such as large specific surface area, chemical stability and numerous functional groups on its surface has become a hot topic in recent years.1 It has been remarkable option as noted candidates for supported of metal nanoparticles such as TiO2,2 Pd,3 Ag,4 and Pt.5 Magnetic Fe3O4 has been widely investigated for several applications such as drug delivery,6 biosensors,7 and bioseparation.8 Recently, the combination of magnetic Fe3O4 with other material has gained considerable attention in separation science. In this study, we report the preparation of magnetic graphene oxide supported metal nanoparticles with relatively high yield and characterization is undertaken by various selected techniques, including SEM, EDX, TGA, XRD and FT-IR.
