One‐step Synthesis of Organic Terminal 2D Ti₃C₂Tx MXene Nanosheets by Etching of Ti₃AlC₂ in an Organic Lewis Acid Solvent

The surface and interface chemistry are critical for controlling the properties of two-dimensional transition metal carbides and nitrides (MXenes). Numerous efforts have been devoted to the functionalization of MXenes with small inorganic ligands; however, few etching methods have been reported on the direct bonding of organic groups to MXene surfaces. In this work, we demonstrated an efficient and rapid strategy for the direct synthesis of 2D Ti
