Sonochemical edge functionalisation of molybdenum disulfide

Abstract

We demonstrate the spontaneous edge functionalisation of molybdenum disulfide nanosheets exfoliated in acetone. Formation of molybdenum oxides explains the observed high-quality and stability of the dispersion in a low boiling point solvent.

Strategies to improve electrocatalytic and photocatalytic performance of two-dimensional materials for hydrogen evolution reaction

“…These stripping methods include techniques such as liquid-phase exfoliation and plasma-assisted exfoliation; among these, liquid-phase exfoliation is most widely used [32,[140][141][142]. The disadvantages of this method are the high manufacturing costs and the difficulty of mass-producing large quantities of the products [143][144][145]. In 2014, Xu et al [146] commented on the mechanism of liquid-phase exfoliation in detail.…”
