Review of strategies for improving the performance of alkaline MXene materials
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.
