摘　　要：无机类石墨烯属于准二维纳米结构体系,因其具有比纯碳石墨烯本身更多的调控参数,比如带隙类型及其带隙宽度可调节等,在电子器件构筑和能量转化存储等领域有着重要的科学意义和广阔的应用前景.近年来,具有准二维特征的金属硫属化合物(metalchal cogenides,MCs)作为类石墨烯结构的重要材料体系受到了广泛关注.本文概述了近年来金属硫属化合物类石墨烯结构的化学制备方法及其可能的组装应用,提出了通过系列方法影响层间作用力及利用晶体各向异性等材料设计与合成策略来实现类石墨烯的化学合成,并展望了类石墨烯的组装结构在能量存储与智能传感领域的应用前景.Inorganic graphene analogues are regarded as a typical quasi-two-dimensional nanostructure system. Graphene analogues entail more structural parameters that could be controlled compared with the pure-carbon graphene, which leads to the well controlled energy-band type and gap width, showing the promising signs in constructing electronic device in the field of energy conversion and energy storage. In this regard, metal chalcogenides （MCs） have drawn extensive attention as an important graphene analogue material system due to its unique quasi-two dimensional crystallographic structure. Herein, we reviewed the synthesis and assembly methodologies for graphene analogues of MCs, as well as their functional applications of their assembled nanostructures. We put forward the strategies that utilizing chemical methods to weaken interlayer force and embodying the highly anisotropic characteristics in the internal structural lattices to successfully realize the fabrication of graphene analogues. Finally, we also summarized the assembly strategy of graphene analogues and their promising applications in the area of energy storage and intelligent responsiveness nanodevices.
