Abstract

The majority of etching methods for synthesizing MXenes use water as the main solvent, which in turn limits direct use of MXenes in water-sensitive applications. In this work, we show that it is possible to etch, and delaminate, MXenes in the absence of water by using organic polar solvents and ammonium dihydrogen fluoride. We also demonstrate that electrodes made from Ti₃C₂T_z etched in propylene carbonate, resulted in Na-ion battery anodes with double the capacity to those etched in water.
