Intercalated MXene-based layered composites: Preparation and application

Publication date: Available online 21 February 2020Source: Chinese Chemical LettersAuthor(s): Shumeng Wu, He Wang, Li Li, Meixia Guo, Zhichong Qi, Qingyou Zhang, Yanmei ZhouAbstractCombining high conductivity, hydrophilicity and excellent electrochemical performance in one, MXenes have attracted increasing attention since their inception. However, easy to stack caused by the van der Waals’ force between the layers limits their practical application. Fortunately, intercalating other substances between layers of MXenes and getting intercalated MXene-based layered composites (IMLCs) with open structure can improve their physical and chemical properties effectively. Larger available surface helps expose more active sites and enlarged layer spacing facilitates ion transport. In addition, other substances fixed in the interlayers by MXenes’ two-dimensional confinement effect can produce synergistic effect and expand their applicable range greatly. This review is dedicated to summarizing the preparation methods and applications of IMLCs, emphasizing the advantages of them in the fields of energy storage, catalysis, sensors, electromagnetic interference (EMI) shielding and biomedicine. Furthermore, prospects and further developments in these gratifying fields are also commentedGraphical AbstractIntercalated MXene-based layered composites have enormous potentials due to their more available active sites, larger interlayer space and synergistic effect of each component.
