Electrochemical analysis of Solvothermally synthesized MoS2 nanostructures for high performance supercapacitor

This study investigates the influence of different solvents, including ethylene glycol (EG), dimethylformamide (DMF) and water, on the structure and electrochemical properties of MoS2 synthesized via a single-step pot synthesis technique. These solvents facilitate the formation of MoS2 nanostructures with diverse dimensions. The synthesized material was analyzed using XRD, FTIR, Raman spectroscopy, FE-SEM and BET analysis. The hierarchical microflower structure of MoS2, with exfoliated edge-enriched nanosheets, exhibited the highest specific capacitance of 428 F g(-1) at 1 mV s(-1) and 280 F g(-1) at 1 A g(-1) when synthesized using water as a solvent, surpassing the results achieved with other solvents. The MoS2 nanostructure-based symmetric supercapacitor achieved an energy density of 7.5 Wh kg(-1), a power density of 1980 W kg(-1) and retained similar to 95 % capacitance after 1000 cycles at 2 A g(-1), highlighting its potential for future applications with exceptional stability and durability.
