Delamination of Chlorine-Terminated MXene Produced Using Molten Salt Etching

MXenes produced by Lewis acid molten salt (LAMS) etching of MAX phases have attracted the community’s attention due to their controllable surface chemistry. However, their delamination is challenging due to the hydrophobicity of the produced multilayer MXene and strong interactions between the halogen-terminated MXene sheets. The current delamination method involves dangerous chemicals such as n-butyllithium or sodium hydride, making scale-up difficult and limiting the practical application of this class of MXenes. In this work, we present a simple and efficient method for the delamination of MXenes from the LAMS synthesis while maintaining their surface chemistry. LiCl salt and anhydrous polar organic…
