▎ 摘  要

NOVELTY - Making nanosheets, comprises providing a mixture comprising a bulk material and a solvent mixture, where the solvent mixture comprising a transition metal nitrate, an acid, a non-polar solvent, and a dispersant, and treating the mixture with an ultrasound treatment to exfoliate nanosheets from the bulk material. USE - The method is useful for making nanosheets, which are useful in a solvent mixture (claimed) and in materials applications e.g. graphene and transition metal di-chalcogenides. ADVANTAGE - The method: provides high yield of 73-81% and high-quality nanosheets; and utilizes low frequency that avoids breaking the nanosheets into smaller pieces. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a solvent mixture for making nanosheets, comprising a non-polar solvent, a dispersant, a transition metal nitrate, and an acid.
