One pot synthesis of MoO3/MoS2 composite and investigation on its electrochemical charge storage properties

Transition metal compounds are widely used in electrochemical energy storage application due to their variable oxidation state. Molybdenum disulfide is one of the important transition metal dichalcogenide, with layered structure similar to graphene. Here we report one-pot synthesis of MoS2/MoO3 nanocomposite for the electrochemical energy storage electrode application. Crystal structure of the as-prepared composite is confirmed by XRD analysis. The achieved maximum specific capacitance for MoS2/MoO3 nanocomposite is 303 F/g at 1 A/g current density. An excellent rate capability of 77.2% is attained at 10 A/g. The enhanced specific capacitance and good capacitive retention is due to the collective contribution from both the material. Hence we propose MoS2/MoO3 nanocomposite as an efficient material for electrochemical energy storage application.Transition metal compounds are widely used in electrochemical energy storage application due to their variable oxidation state.
