Effect of solvent on the morphology of MoS2 nanosheets prepared by ultrasonication-assisted exfoliation

Abstract

The MoS<inf>2</inf> nanosheets are prepared via liquid-phase exfoliation route. Bulk MoS<inf>2</inf> powder is exfoliated by ultrasonication-assisted method with the aid of different solvents. The effect of solvents used on the morphology of the MoS<inf>2</inf> nanosheets is investigated. The exfoliated material is analysed by using scanning electron microscopy, transmission electron microscopy, Fourier-transform infrared spectroscopy and X-ray diffractometry. The MoS<inf>2</inf> nanosheets exfoliated by using NMP-water mixture showed the better morphology than that exfoliated with the other solvent mixtures. © 2018 Author(s).
