摘要
拥有片层结构的二维过渡金属氮化物和碳化物(MXene)纳米材料是新发现的一种二维材料,可以通过氢氧化钠处理改变MXene材料表面的官能团和官能团的数量,经碱处理过的MXene材料拥有更优良的电化学、吸附等性能,可应用于能量储存和转换、光电催化、柔性传感器等领域。对提升碱化MXene材料性能的策略进行综述。首先可以通过十八烷基胺、氨基、金属离子等小分子修饰碱化MXene材料,还可以通过碱化MXene与金属材料、金属化合物、非金属材料、高分子材料等复合得到复合材料从而提升其性能。还对碱化MXene的发展提出了建议,认为调控碱化MXene材料的性能并降低碱化MXene材料的生产成本是拓展碱化MXene材料实际应用的主要方向。
The two-dimensional transition metal nitride and carbide(MXene)nanomaterial with a lamellar structure is an emerging class of two-dimensional material.The variety and the number of functional groups on the surface can be further altered by treating with sodium hydroxide,resulting in alkali-treated MXene materials with superior electrochemical and adsorption properties.And it can be applied in the fields of energy storage and conversion,photoelectrocatalysis,and flexible sensors.In this review,strategies for improving the performance of alkaline MXene materials are introduced.Firstly,alkaline MXene materials can be modified by small molecules such as octadecylamine,amino acid,and metal ions.Additionally,composites can be obtained by combining alkalized MXene with metal materials,metal compounds,non-metallic materials,and polymer materials to enhance their performance.Recommendations for the development of alkalized MXene have been provided,indicating that regulating the properties of alkaline MXene materials and lowering the production cost are the main approaches to broaden their applications.
