One-step microwave synthesis of MoS2/MoO3@graphite nanocomposite as an excellent electrode material for supercapacitors

We introduce a facile one-step microwave solid-state approach to prepare novel MoS 2 /MoO 3 @graphite nanocomposite that can be utilized as an electrode material for supercapacitors. The electrochemical properties of nanocomposite are evaluated by cyclic voltammetry, galvanostatic charge/discharge, and electrochemical impedance spectroscopy tests. The nanocomposite exhibits the highest specific capacitance of 268 F g −1 for 3500 cycles at a current density of 1 A g −1 . The nanocomposite shows excellent cyclic stability of 283% (258 F g −1 ) for over 6000 cycles in 6 M KOH electrolyte. In addition, the microwave method, which is prospected to realize industrial application, can be applied to partial sulfurization. Schematic diagram of microwave initiated MoS 2 /MoO 3 nanocomposite growth on graphite, and the highly stable MoS 2 /MoO 3 @graphite nanocomposite was synthesized using this one-step microwave approach.
