In materials science, MXenes are a class of two-dimensional inorganic compounds. These materials consist of a transition metal carbide, nitride or carbonitride layer several atoms thick. MXenes was first described in 2011. Because of its hydroxyl or oxygen-terminated surface, MXenes combines the metal conductivity of transition metal carbides with hydrophilicity.

Synthetic MXenes prepared by HF etching have an accordion-like morphology. When there are less than five layers, they can be called multi-layer MXene (ML-MXene) or several layers of MXene (FL-MXene). Because the surface of MXenes can be terminated by functional groups , So you can use the naming convention M n+1 X n T x, where T is a functional group (such as O, F, OH, Cl).

Single transition metal MXenes

MXenes adopts three structures. There is a metal at the M site, inherited from the parent MAX phase: M 2 C, M 3 C 2 and M 4 C 3. They are produced by selectively etching the A element from the MAX phase or other layered precursors (for example, Mo 2 Ga 2 C), and have the general formula M n+1 AX n, where M is an early transition metal, A is an element of group 13 or 14 of the periodic table, X is C and/or N, and n = 1–4. The MAX phase has a layered hexagonal structure with P6 3/mmc symmetry, in which the M layer is almost closed and stacked, and the X atoms fill the octahedral sites. Therefore, the M n+1 X n layers are interlaced with the A element, and the A element is bonded to the M element metal.

Double transition metal MXenes

Double transition metal MXenes can have two forms, ordered double transition metal MXenes or solid solution MXenes. For ordered double transition metal MXene, they have the general formula: M'2 M” C 2 or M'2 M” 2 C 3 where M'and M” are different transition metals. Synthesized double transition metal carbides Including Mo 2 TiC 2, Mo 2 Ti 2 C 3, Cr 2 TiC 2 and Mo 4 VC 4. In some of these MXenes (such as Mo 2 TiC 2, Mo 2Ti 2 C 3 and Cr 2 TiC 2), Mo or Cr atoms are located on the outer edge of MXene, and these atoms control the electrochemical properties of MXene.

For solid solution MXene, they have the general formula: (M' 2−y M" y)C, (M' 3−y M" y)C 2, (M' 4−y M" y)C 3, or (M '5−y M" y) C 4, where the metal is randomly distributed in the solid solution throughout the structure, resulting in continuous and customizable characteristics.
