摘要：

We report a facile strategy to synthesize of polypyrrole/molybdenum disulfide (PPy/MoS2) nano-composite as an advanced electrode material for high-performance supercapacitors applications. Flowerlike MoS2 with graphene-like subunits structure is prepared using a hydrothermal method, and the nanocomposite PPy are embedded in MoS2 nanosheets is prepared by in situ oxidation polymerization of pyrrole in the presence of MoS2 suspension. Structural and morphological characterizations of the nanocomposite are investigated by XRD, FE-SEM and TEM measurements. Their electrochemical properties are also investigated using cyclic voltammetry, and galvanostatic charge/discharge. The PPy/MoS2 nanocomposite exhibit high specific capacitance of 553.7 F g(-1) and its capacitance can still remain 90% after 500 cycles at a current density of 1 A g(-1). (C) 2012 Elsevier B.V.
