【摘要】 MXene是一类新型碳/氮化物二维纳米层状材料,一般是利用化学刻蚀的手段通过选择性刻蚀掉前驱体MAX相中的A原子层而得到。其通式可表示为M_n+1X_nT_x,其中M代表早期过渡族金属,X代表碳和/或氮,T_x代表MXene在刻蚀过程中产生的附着在其表面的官能团（-OH、-F、=O、等）。采用一定的手段将多层MXene剥落,可获得类石墨烯形貌的单层MXene。MXene除了具备传统二维材料的性能外,还兼具良好的导电性、亲水性、透光性、柔韧性以及能量储存性能,在复合材料、润滑剂、环境污染治理、电池、电容器、催化、传感器、抗菌等领域具有潜在的应用价值。文章总结了MXene的制备、结构、性能和应用等方面的最新成果,并展望了其今后的研究方向。更多还原

【Abstract】 MXene is a group of newly emerging two-dimensional（2-D）carbide/nitride materials,which are derived from its precursor MAX phase by selectively extracting A atoms from MX layers using chemical etching method.MXene can be denoted as M_n+1X_nT_x,where M is an early transition metal,X is carbon and/or nitrogen,and T_xrepresents surface termination groups（-OH,-F,=O）created in the etching progress.Single layered MXene exfoliated from multi-layered MXene resembles the morphology of graphene.Besides its merits of classical 2-D materials,MXene shows superior characteristics of high electrical conductivity,hydrophilia,transparency,flexibility and energy storage,which confer MXene on promising applications in composites,lubricant,environmental pollution abatement,batteries,capacitors,catalysts,sensors,antibacterial etc.This article presents the latest research results of the synthesis,structure,properties and potential applications for MXene,and research directions for MXene in the future are also predicted.更多还原
