MXene material was discovered in 2011, is one of the most concerned two-dimensional nanomaterials after graphene, rapid development in recent years, has become the forefront of materials, energy, catalysis, environmental protection, sensing and many other fields of research.
Introduction to MXene materials
Two-dimensional transition metal carbides, nitrides or carbon nitrides, namely MXene materials, are A new class of two-dimensional nanomaterials obtained by layer ceramic material MAX phase etching after removing element A. This designation both reflects the material's origin from the MAX phase and highlights its characteristics of a two-dimensional lamellar structure like graphene. The chemical formula of MXene can be expressed as Mn+1XnTx, where M stands for pre-transition metal elements (Sc, Ti, V, Cr, Zr, Nb, Mo, etc.), X stands for C or/and N elements, and Tx stands for surface end groups (-O, -OH, -F, etc.). Due to the diversity of MAX phase composition and structure, MXene materials derived from it have also become the largest family of two-dimensional materials, with more than 100 theoretical predictions, and more than 40 kinds of synthetic materials have been synthesized.
