Pushing the boundaries of MXenes

MXenes have seen an explosion of interest since Ti₃C₂T_x was synthesized from a MAX phase precursor in 2011. Since then, more than forty stoichiometric two-dimensional transition metal carbides, nitrides, and carbonitrides have been reported, spanning single-M MXenes, disordered (solid-solution) MXenes, and ordered MXenes (in-plane or out-of-plane ordered). Due to their interesting properties, they have been used in applications that include energy storage, catalysis, electromagnetic shielding, devices, biomaterials, and many others. Like other two-dimensional materials, controlling the chemistry and processing of MXenes can substantially alter their behavior. Research has therefore only just started to explore the structure, performance, and application space that is possible with MXenes.

This Collection brings together the latest developments in the burgeoning field of MXenes. Topics of interest include, but are not limited to, the following:

-Development of new MXene compositions

-Synthesis and processing by existing and emerging techniques

-Fundamental understanding of their physics, chemistry, and biological interactions

-Structure and property characterization and control

-Applications demonstrations

We welcome the submission of any paper related to MXenes. All submissions will be subject to the same review process and editorial standards as regular Communications Materials Articles.
