Abstract EN
Exfoliation of bulk molybdenum disulfide (MoS2) using sonication in appropriate solvent is a promising route to large-scale preparation of few-layered or monolayered crystals.
Grinding-assisted sonication exfoliation was used for preparing monolayered MoS2 nanosheets from natural mineral molybdenite.
By controlling the sonication time, larger crystallites could be further exfoliated to smaller as well as thinner nanosheets without damaging their structures.
The concentration of 1.6 mg mL−1 of final solution could be achieved.
Several microscopic techniques like scanning electron microscopy, transmission electron microscopy, and atomic force microscopy were employed to evaluate the exfoliation results.
Strong photoluminescence with the peak centered at 440 nm was also observed in the resulting dispersion which included several small lateral-sized (~3 nm) nanostructures.
