MXene

English

A scanning electron microscope image of the MXene Ti₃C₂

Etymology

A contraction of M_n+1X_n, the general formula for these compounds.

Noun

MXene (plural MXenes)

1. (materials science) Any of a class of inorganic compounds with the general formula M_n+1X_n (where M is an early transition metal and X is carbon or nitrogen), characterized by a layered structure. [from 2011]

     Generally, MXenes were synthesized by the chemical etching method where chemical etching agents were used to etch off one of layers within ABC-type trielemental layered compounds.
