Description
Summary:Discovery of graphene and its distinctive set of properties and application worthiness led to a massive increase in researcher’s attention in two-dimensional layered materials. There are various two-dimensional layered materials like graphene, graphyne, borophene, germanene, silicene, hexagonal boron nitride, MXenes, and transition metal dichalcogenides. Transition metal dichalcogenides especially dichalcogenide of molybdenum are being recognized as an alternative to graphene, due to their exceptional properties and potential for use in various domains. Owing to high surface area and high aspect ratio, nanostructured materials and nanocomposites have been recognized as potential field emitters and supercapacitor electrode. Therefore, an attempt has been made to hydrothermally synthesize MoS 2 nanoflowers on carbon paper and investigate their field emission and super-capacitive behavior. We have demonstrated that MoS 2 –carbon paper nanocomposite can be competitive with various other well-known field emitters. Further, we have established that a stable field emission current can be measured with a turn-on field as low as 0.94 V/μm and a field enhancement factor up to ~ 5373 at 1 mm cathode–anode separation. Owing to the low turn-on field and its morphology, MoS 2 –carbon paper nanocomposite could be explored for field emission-based displays, field emission lamps, and vacuum electronic components and devices. The highest specific capacitance of 137 F.g −1 was calculated for NaOH electrolyte and highest saturation potential is observed for Na 2 SO 4 electrolyte. For NaOH, the area under the curve decreases with increasing electrolyte concentration, and the maximum area under the curve is observed in the case of 0.5 mol.cc −1 concentration. Along with field emission application, the experimental results also propose the multifunctional potential of MoS 2 –carbon paper nanocomposite in super-capacitors and energy storage.
