摘要:: 石墨烯的发现掀起了人们对二维晶体材料的探索热潮。单层或少数层过渡金属硫族化合物（TMDs）是二维晶体材料的典型代表，此类材料的带隙合适、电子迁移率和热导率高、光吸收强、比表面积大，在新型光电器件、光/电催化、锂离子电池电极、气体传感及生物医学等领域蕴藏着巨大的应用潜能。特别是，对于TMDs二维晶体与其他材料复合而成的纳米结构，强烈的界面耦合作用对材料物理和化学特性的调控至关重要，甚至可能导致新奇特性，预示着新功能和新应用。本论文详细综述了TMDs二维晶体基复合材料的制备方法、结构与性能的界面调控及其潜在应用，并指出了该研究领域仍存在的问题及未来发展方向。

Abstract:: The discovery of graphene promotes the exploration of two-dimensional (2D) materials. Single-layer or few-layer transition metal dichalcogenides (TMDs) are the representative ones, and they exhibit enormous potential applications in many high-tech fields, such as, electronic devices, photo/electro-catalysis, batteries, sensors, and so on, owing to adjustable band gap, high electron mobility and thermal conductivity, strong light absorption and large specific surface area. Especially, as for the TMDs-based 2D composites, the strong interfacial coupling is crucial to optimize their physical and chemical properties, which even induces novel properties and generates new functions for practical applications. The fabrication methods, interfacial coupling effects and applications are systematically summarized and discussed. Accordingly, the challenges and opportunities in this promising research area are also presented.
