Large-quantity and continuous preparation of two-dimensional nanosheets

Abstract

With the increasing demand for two-dimensional (2D) nanosheets, such as graphene, hexagonal boron nitride (h-BN), and MoS₂ and WS₂ nanosheets, finding a simple and feasible method to obtain nanosheets is crucial. Here, we present a high-efficiency exfoliation method to obtain abundant and superior graphene, h-BN, MoS₂, and WS₂ nanosheets in aqueous solution. The obtained 2D nanosheets are very thin, especially MoS₂ and WS₂ nanosheets which are below 1 nm.
