Exfoliation, delamination, and oxidation stability of molten salt etched Nb₂CT_<i>z</i> MXene nanosheets

Abstract

molten salt etching and utilizing a KOH wash to add hydroxyl surface groups. However, little is known about the oxidation of molten salt etched MXenes compared to acid-etched MXenes. Our results indicate slower oxidation behavior for MXenes etched by molten salts, which may be due to the decreased amount of oxygen-containing terminal groups.
