| Abstract Scope |
MAX phases are a chemically versatile family of ternary carbides, nitrides and carbonitrides that combine characteristics of metals and ceramics. Historically the interest in MAX phases has been related to their intriguing mechanical properties, and they are therefore not typically discussed as functional materials. In a different setting, they serve as bulk precursors for a relatively young class of 2D materials, the MXenes that can be synthesized from MAX phases by means of chemical etching.
I will discuss our group’s efforts to synthesize new versions of MAX phases and MXenes in terms of their chemical composition and morphology. The structure of the compounds is analyzed in detail by different diffraction techniques and electron microscopy. Additional spectroscopy techniques allow insights into the chemistry of intermediate species and the final products. The functional properties of the new types of materials include magnetic and electronic properties as well as electrocatalytic performance. |
