Synthesis of high quality 2D carbide MXene flakes using a highly purified MAX precursor for ink applications.

ABSTRACT: The practical application of 2D MXenes in electronic and energy fields has been hindered by the severe variation in the quality of MXene products depending on the parent MAX phases, manufacturing techniques, and preparation parameters. In particular, their synthesis has been impeded by the lack of studies reporting the synthesis of high-quality parent MAX phases. In addition, controllable and uniform deposition of 2D MXenes on various large-scale substrates is urgently required to use them practically. Herein, a method of pelletizing raw materials could synthesize a stoichiometric Ti₃AlC₂ MAX phase with high yield and processability, and fewer impurities. The Ti₃AlC₂ could be exfoliated into 1-2-atom-thick 2D Ti₃C₂T
