摘　　要：以石墨烯、MoS2、MXene等为代表的二维材料具有优异的物理、化学、电子和光学性能,在诸多领域具有巨大的应用价值。第36届和第37届中国化学奥林匹克(初赛)以二维材料LDH和MXene的结构和制备为素材命题。分析和拓展试题素材中的LDH和MXene,介绍制备二维材料的“top-down”策略,帮助师生深入理解物质结构、性质和应用之间的关系。Two-dimensional materials represented by graphene,MoS2,MXene,etc.show excellent physical,chemical,electronic,and optical properties,and exhibit enormous application value in many fields.The 36th and 37th Chinese Chemistry Olympiad(preliminary)focused on the structure and preparation of LDH and MXene.This article delves into and expands upon the materials of LDH and MXene,and introduces the“top-down”strategy for preparing two-dimensional materials,aiding teachers and students in deepening their understanding of the relationship between material structure,properties,and applications.
