The Rise of MXenes

The variety of compositions and structures of MXenes has led to the formation of a large and rapidly expanding family of 2D materials. In the past 2 years, the MXenes field has seen significant increases in the numbers of research areas and publications. The formation of solid solutions on M and/or X sites offers possibilities for the synthesis of an infinite number of nonstoichiometric MXenes and an attractive opportunity to finely tune properties by mixing different transition metals or creating carbonitrides. The large, underexplored family of MXenes and their unique combination of properties opens the door to a variety of different applications, and the possibilities of new compositions make the readr believe that the people are still in the early days of MXene research and many exciting discoveries are to come.
