Layered 2D transition metal dichalcogenides (TMD’s) have been considered as an important class of materials in the field of energy and environmental applications. Therefore, it is desirable to fabricate 2D hybrid TMD’s materials in simple solution processing methods. In this study, MoS2-RGO hybrid 2D few layered sheets are produced by supercritical fluid process (SCF) by using ethanol as solvent at 250 ºC in a short duration of 0.5 h. Atomic force microscopy (AFM), transmission electron microscope (TEM) and scanning electron microscope (SEM) images confirmed the formation of 2D hybrid few layered sheets. The electrochemical impedance measurement indicates fivefold increase in conductivity of bulk MoS2. This work presents rapid and one pot exfoliation of MoS2 and simultaneous reduction of GO that can facilitate the production of 2D hybrid materials.
