2D nanomaterials for Energy Storage

Abstract

Our aim is to develop ultrathin 2D-nanomaterials which can be used for energy storage and photo-catalysis. The most popular candidate for this purpose is graphene Nano-sheets, which are obtained from graphite by chemical exfoliation method. The application of graphene in the field of electrochemical energy storage devices has been extensively investigated due to its many promising physical and chemical properties. Graphene is a flat monolayer of carbon atoms with perfect sp-hybridized two- dimensional carbon structure. It has high conductivity, superior electron mobility, extremely high specific surface area, excellent optical transmittance and easy functionalization makes graphene a good substrate to produce graphene based composites for energy storage. Especially, graphene – Metal Chalcogenides (e.g. WS2, MoS2, etc.) composites that have attracted extensive attention for their potential applications in energy related areas.
