MoS2 based nanocomposites: An excellent material for energy and environmental applications.

Molybdenum disulphide (MoS 2) is a transition metal dichalcogenide most widely studied as a heterogeneous catalyst due to its outstanding structural and physicochemical properties. Today, 2D layered MoS 2 has gained much attention due to its variety of environmental remediation applications, production of cleaner fuels, and energy storage. MoS 2 is a structural analogue of graphene and has similar properties, like greater surface area, a good charge carrying capacity, and higher mechanical strength. Therefore, MoS 2 can be easily coupled with graphene to further enhancing its catalytic efficiencies. Moreover, MoS 2 is less costly, highly abundant, has better light absorption capacity and adjustable bandgap than graphene. Most of the recent advancements in structural and synthesis techniques for improving catalytic properties of MoS 2 for various applications like photodegradation of dyes and organic compounds, hydrogen production, dye-sensitized solar cells, electrochemical capacitors, hydrodesulfurization, chemical and biological sensors, and gas sensors are discussed in this paper. Future prospective and research topics for the development of MoS 2 based composites are also discussed.
