二维(2D)过渡金属碳化物、碳氮化物和氮化物家族，称为MXenes，已从2011年的单一成分发展到类似于50种成分的家族。MXenes具有大量可能的过渡金属及其组合，单个2D薄片的四个可能的2D厚度范围，可调的表面化学以及在2D薄片之间承载物种的能力，MXenes可以被认为是2D空间中最易修改的材料家族之一。MXenes具有与其他2D材料互补的独特性能组合，例如高电导率(高达24,000 S/厘米)、高杨氏模数(达到约380 GPA)、2D弹性以及可调和亲水性表面。这些性质及其简单和可扩展的合成使MXenes有资格在各种不同的领域进行研究，包括能量存储和转换、电催化、传感、电磁干扰屏蔽和无线通信、结构材料、摩擦学、环境修复和生物医学领域。本期涵盖了MXenes的各种合成路线以及MXenes在传感、环境和生物医学应用方面的一些新兴领域。此外，还从计算研究的角度讨论了MXenes的结构、稳定性和性质。
The family of two-dimensional (2D) transition-metal carbides, carbonitrides, and nitrides, known as MXenes, has grown from a single composition in 2011 to a similar to 50-composition family. With a large number of possible transition metals and their combinations, four possible 2D thickness ranges for a single 2D flake, tunable surface chemistry and the capability for hosting species between their 2D flakes, MXenes can be considered one of the most amendable families of materials in the 2D space. MXenes have a unique combination of properties complementary to other 2D materials, such as high electrical conductivity (up to 24,000 S/cm), high Young's modulus (reaching similar to 380 GPa), combined with 2D flexibility, and tunable and hydrophilic surfaces. These set of properties as well as their simple and scalable synthesis qualified MXenes to be studied in a variety of different areas, including energy storage and conversion, electrocatalysis, sensing, electromagnetic interference shielding and wireless communications, structural materials, tribology, environmental remediation, and biomedical fields. This issue covers the various MXene synthesis routes and some of MXenes emerging areas in sensing, environmental, and biomedical applications. Additionally, the structure, stability, and properties of MXenes are discussed from the computational studies perspective.
