Production of few-layer MoS2 nanosheets through exfoliation of liquid N2–quenched bulk MoS2†
Abstract
We demonstrate an efficient method for the production of few-layer MoS2 nanosheets through exfoliation of bulk MoS2 compounds that were subject to quenching in liquid N2 and subsequent ultrasonication. This solution-based method, which involves a “quenching cracks” phenomenon, was performed open to the atmosphere. Subsequent ultrasonication of the exfoliated MoS2 in solution provided us with MoS2 nanosheets comprising two to four layers.
