Metal Oxide-Graphene Nanocomposites

Abstract

Graphene is one of the most interesting materials in the field of nanoscience and nanotechnology. Metal oxide nanoparticles exhibit unique physical and chemical properties due to their reduced size and high density of corner or edge surface sites. The metal oxide-graphene nanocomposites not only possess favorable properties of graphene and metal oxide, but also greatly enhance the intrinsic properties due to the synergistic effect between them. These composites are used for catalysis, supercapacitors, lithium ion batteries, solar cells, sensors, removal of pollutants from water, etc. There is a very broad scope of further research for the development of metal oxide-graphene nanocomposites with enhanced properties for different applications. This chapter deals with a comprehensive review of the current research activities from the viewpoint of chemistry and materials science with a special focus on the synthesis, characterization, and applications of metal oxide-graphene nanocomposite materials.
