Synthesis and Electrochemical Properties of Molybdenum Disulfide/Graphene Composites

The complex of single-layered molybdenum disulfideMolybdenum disulfide and grapheneGraphene wereSynthesis widelyElectrochemical properties used for capacitor field dueComposites 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 grapheneGraphene , volume ratio of water and ethanol in the solvent were investigated by XRDXRD , SEMSEM and Cyclic Voltammetry test in this work. The XRDXRD and SEMSEM results demonstrated that the loose flower-like spherical molybdenum disulfideMolybdenum 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 disulfideMolybdenum disulfide was further grown on the reduced graphene oxideReduced graphene oxide skeleton. It was found that the specific capacitanceSpecific 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 disulfideMolybdenum disulfide .
