A vertically aligned MoS2 nanosheet-polypyrrole composite on reduced oxygen graphene was fabricated using a one-step hydrothermal strategy (MP-rGO). The MoS2 nanosheets mixed with PPy lamellas were well coated on the surface of rGO to form a ternary nanostructure via a redox reaction. The resulting MP-rGO electrode exhibited high specific capacitance and cycling stability, suggesting potential application in energy storage.
Vertically aligned MoS2 nanosheet-polypyrrole (PPy) composites on reduced oxygen graphene (rGO) are fabricated by a one-step hydrothermal strategy (MP-rGO). The ultrathin MoS2 nanosheets mixed with PPy lamellas are well coated on the surface of rGO to form a ternary nanostructure. PPy lamellas are formed on rGO with MoS2 nanosheets by a redox reaction between ammonium tetrathiomolybdate and pyrrole. The conductivity of MoS2 was effectively improved by using PPy and rGO, and the MoS2/PPy (MP) nanohybrid endows MoS2 low crystalline and PPy amorphous. The MP-rGO electrode exhibits a specific capacitance of 1942 F g(-1) (or 215.8 mA h g(-1)) at a density of 1 A g(-1) and a satisfactory cycling stability. The MP-rGO//AC asymmetric supercapacitor has been assembled and exhibits a high energy density of 39.1 Wh kg(-1) at a power density of 0.70 kW kg(-1), which confirms its potential application in the energy storage.
