Recently, 2D transition metal dichalcogenides (TMDCs) (e.g., MoS_2, WS₂, MoSe₂, WSe₂, MoTe₂, etc.) have been attracting a wide range for research interest due to their favorable mechanical, chemical, electrical and optical properties. Among them, MoS₂ have been widely used as a functional material in diverse fields such as lubrication, electronic transistors, batteries, photovoltaics, and catalysis. Recently it has been also observed that MoS₂ nanostructure is possessing piezoelectric functionality. On the other side PVDF nanofiber based nanogenerator is a good flexible device for scavenging mechanical energy from environment. Nanofiber can be generated by using electrospinning process. In this article a brief idea about PVDF nanofiber preparation is the key focus of this paper. Material and structural analyses on fabricated nanofibers using tools such as XRD (X-ray diffraction), FTIR (Fourier transform infrared), FE – SEM (Field emission scanning electron microscopy) toward the fundamental characterizations of piezoelectric nanofibers are also described. MoS₂ can be incorporate in PVDF for getting better performance of nanogenerator. Here MoS₂ nanosheets preparation and characterization has been done.  Summarize the report by the application of nanofiber based nanogenerator as energy scavenging applications.
