Title: The Rise of MXenes


Carbides and nitrides of transition metals known as MXenes are a fast-growing family of 2D materials. More than 30 different MXenes have been reported, and the structure and properties of numerous other MXenes have been predicted using density functional theory (DFT) calculations. Moreover, the availability of solid solutions on M and X sites, control of surface terminations, and the discovery of ordered double-M MXenes, such as out-of-plane ordered o-MXenes and in-plane ordered i-MXenes, offer the potential for producing dozens of new distinct structures. This presentation will describe the state of the art in the field. The manufacturing of MXenes, their delamination into single-layer 2D flakes and assembly into films, fibers and 3D structures will be briefly covered. Synthesis-structure-properties relations of MXenes will be addressed on the example of Ti3C2. The use of MXenes in ceramic- metal- and polymer-matrix composites, smart fibers and textiles will also be discussed. The versatile chemistry of the MXene family renders their properties tunable for a large variety of applications. Oxygen or hydroxyl-terminated MXenes have redox capable transition metals layers on the surface and offer a combination of high electronic conductivity with hydrophilicity, as well as fast ionic transport. This, among many other advantageous properties, makes the MXene family promising for energy storage and related electrochemical applications, but applications in plasmonics, electrocatalysis, biosensors, electronics, water purification/ desalination and other fields are equally exciting.
