Layered 2D transition metal dichalcogenides (TMD’s) have been considered as an important class ofmaterials in the field of energy and environmental applications. Therefore, it is desirable to fabricate2D hybrid TMD’s materials in simple solution processing methods. In this study, MoS2-RGO hybrid2D few layered sheets are produced by supercritical fluid process (SCF) by using ethanol as solvent at250 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 fewlayered sheets. The electrochemical impedance measurement indicates fivefold increase in conductivityof bulk MoS2. This work presents rapid and one pot exfoliation of MoS2 and simultaneous reductionof GO that can facilitate the production of 2D hybrid materials.
