2D Carbides and Nitrides (MXenes) for Energy and Environmental Technologies
Following the discovery of 2D Ti3C2 in 2011, 2D carbides, oxycarbides, carbonitrdes and nitrides of transition metals known as MXenes [1] have greatly expanded the nanomaterials family. More than 50 different MXenes have been reported, and the structure and properties of numerous other MXenes have been predicted. Moreover, the availability of solid solutions on M and X sites, multi-element high-entropy MXenes, control of surface terminations, and the discovery of out-of-plane ordered double-M o-MXenes (e.g., Mo2TiC2), as well as in-plane ordered i-MXenes offer a potential for producing dozens of new distinct structures and virtualy an infinite number of compositions. This presentation will describe the state of the art in the synthesis of MXenes, their delamination into single-layer 2D flakes and processing into films, fibers and 3D structures. Synthesis-structure-properties relations of MXenes will be addressed on the example of Ti3C2. The versatile chemistry of the MXene family renders their properties tunable for a large variety of applications, including energy storage and water purification/desalination
