Application of Graphene for Producing of Clean Energy

The increasing consumption of fossil fuels and limited resources and the environmental problems cause to carry out extensive research on the replacement of new and clean energy resources. In recent years, researchers have focused on fuel cells, solar cells, lithium batteries and biomass as a clean energy reserves. Although these methods have disadvantages but the using of nanotechnology lead to solve significant drawback of these techniques. Graphene, as a carbon nanostructure, is a two-dimensional substance with hexagonal network and covalent bonds have unique properties including high electrical, mechanical, thermal, chemical, surface area and low density. These wonderful properties lead to graphene is considered as a good candidate in fuel cell, solar cell, ion battery and bio mass. Due to the importance of this issue, this paper reviews the graphene and its applications in clean energies.
