Graphene Oxide Based Metallic Nanoparticles and their Some Biological and Environmental Application

Recently the decoration of graphene with metallic nanoparticles by a synchronized reduction of graphene oxide (GO) and synthesis of metallic nanoparticles has gained momentum. Metal-decorated carbon substrates, for example, carbon nanotubes and graphene oxide have been of interest to the scientific group all through the past three decades on account of different potential applications. The utilization of graphene oxide as the nano scale substrates for the formation of nanocomposites with metal oxides is a novel thought to acquire a hybrid which would show both the properties of GO as an interesting paper-shape material and the elements of single nanosized metal particles.Graphene is a carbon allotrope of sp2 hybridized carbon atoms in a honeycomb lattice. It has attracted unique properties and potential applications. It has been synthesized and modified through various methods, and composites have been made with other nanomaterials, such as metals, metal oxides, and some complex oxides.Grapheme-metal oxide composites are gaining attention as a viable alternative to boost the efficiency of various catalytic, storage reactions in energy conversion, anticancer and drug delivery applications. Nevertheless, by combining the superior physical/chemical properties of GO themselves and the versatile nanomaterials that can decorate with GO, GO based materials have a bright future in the anticancer, drug delivery, energy, and environmental applications.This review article has described the recent publications in the development of Decoration of Graphene Oxide such as metals, metal oxides and their nanocomposites based materials. We anticipate this active field will continue growing rapidly, leading eventually to a variety of mature materials and devices that would benefit the society. Finally, the applications of composites are at their initial stages. They need to be studied systematically from both theoretical and experimental aspects.
