Abstract
The development of graphene/nanoparticles composites materials is currently the issue of tremendous research interest. Graphene sheets possess surface defects and oxygen functional groups, which make them ideal templates for synthesis of semiconductor and metal nanoparticles. To date graphene have created an immense research interests because of its excellent electronic, optical, mechanical, and thermal properties, graphene has shown great promises in a wide range of applications such as photovoltaic application, energy storage devices, photocatalytic hydrogen evolution, and gas sensing application. Enhanced properties are expected in these graphene/nanoparticles composites, which arise from the synergic effect of the graphene sheets anchored nanoparticles. In this review, after introduction on the properties and the various synthesis methods of graphene/nanoparticles, we will discuss the application of graphene/nanoparticles composites specially graphene/semiconductor nanoparticles composites, in fields of Photovoltaic application, energy storage, Photocatalytic hydrogen evolution and gas sensing application.
