Figure 1. Synthesis of MXene. (A) The constituent elements of MXene, with the three structures of MXene at the bottom; (B) Elements employed in synthesizing MAX phases, MXenes, and their intercalated ions. The blue-striped element is limited to the MAX phase system, whose MXene has still not been successfully prepared. The red background element points to the etchability of A element in the MAX phase. The green background corresponds to the set of cations for which MXene embedding has been accomplished. Reproduced with permission^[27].
