发布时间:2019-05-29 14:00
【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。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 has set off an upsurge in the exploration of two-dimensional crystal materials. Single-layer or a few transition metal sulfur compounds (TMDs) are typical representatives of two-dimensional crystal materials. These materials have suitable band gap, high electron mobility and thermal conductivity, strong optical absorption, large specific surface area, and photocatalysis in new optoelectronic devices. Lithium ion battery electrode, gas sensing and biomedicine have great application potential. In particular, for the nanostructures composed of TMDs two-dimensional crystals and other materials, the strong interfacial coupling is very important to the regulation of physical and chemical properties of materials, and may even lead to novel properties, indicating new functions and applications. The preparation methods, interface control of structure and properties of TMDs two-dimensional crystal matrix composites and their potential applications are reviewed in detail, and the existing problems in this research field and the future development direction are pointed out.
