Two-dimensional (2D) materials are attracting significant attention due to their unique properties. The most famous example is graphene, an atomically thin layer of carbon atoms: but recently an entirely new family of 2D materials, early transition metal carbides and carbonitrides, was discovered.

The selective etching of the A-group element from a MAX phase results in the formation of these 2D layered materials, dubbed “MXenes”; of which eleven different carbides and carbonitrides have been reported to date. With potential applications in batteries, Li-ion capacitors, supercapacitors, catalysis, water purification/desalination, gas storage and separation, sensors, thermoelectrics, and structural/multifunctional composites, this fascinating family has significant potential contribute to the expanding list of technologies driven by advanced nanomaterials.
