Two-dimensional MXenes

The family of two-dimensional (2D) transition-metal carbides, carbonitrides, and nitrides, known as MXenes, has grown from a single composition in 2011 to ~50-composition family. With large number possible transition metals their combinations, four 2D thickness ranges for flake, tunable surface chemistry the capability hosting species between flakes, MXenes can be considered one most amendable families materials space. have unique combination properties complementary other materials, such high electrical conductivity (up 24,000 S/cm), Young’s modulus (reaching ~380 GPa), combined with flexibility, hydrophilic surfaces. These set well simple scalable synthesis qualified studied variety different areas, including energy storage conversion, electrocatalysis, sensing, electromagnetic interference shielding wireless communications, structural tribology, environmental remediation, biomedical fields. This issue covers various MXene routes some emerging areas environmental, applications. Additionally, structure, stability, are discussed computational studies perspective.
