Abstract
The complex of single-layered molybdenum disulfide and graphene were widely used for capacitor field due to its better stability skeleton, higher specific surface area and conductivity. The morphology and electrochemical performance of the complex with special emphasizing effect of the amounts of graphene , volume ratio of water and ethanol in the solvent were investigated by XRD , SEM and Cyclic Voltammetry test in this work. The XRD and SEM results demonstrated that the loose flower-like spherical molybdenum disulfide could be successful synthesized at a reaction temperature of 200 °C for 24 h, a molybdenum–sulfur ratio of 1:28. And the flower-like spheroidal molybdenum disulfide was further grown on the reduced graphene oxide skeleton. It was found that the specific capacitance reached 45.4 F/g through the cyclic voltammetry test when the solvent is water. Through the AC impedance test, it was found that the addition of rGO improved the conductivity of molybdenum disulfide .
