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.
