MXenes刻蚀剥离研究进展OA

Since the first report of Ti3C2Tx in 2011,the family of two-dimensional transition metal carbides,nitrides,and carboni-trides(MXenes)has grown substantially.Although many predicted MXenes have not yet been experimentally synthesized,theoretical studies indicate that they exhibit promising properties.To advance the synthesis,optimization,and scalable preparation of MXenes,a deeper mechanistic understanding of the complete process is essential,encompassing precursor etching,delamination,and the accom-panying steps of intercalation and exfoliation.Accordingly,this review systematically analyzes various etching strategies for MXenes,including fluorine-based etching,molten salt etching,electrochemical etching,and halogen vapor-phase etching,along with associ-ated delamination methods.Finally,future research directions in the etching and exfoliation of MXene materials are outlined.
