摘　　要：二维沸石纳米片结合了二维纳米材料特殊的物理化学性质以及沸石独特的孔道结构,具有电子限域特征、原子厚度、超高的比表面积和大比例的暴露原子,在石油化工、精细化学和能源环境等领域具有广阔的应用前景。加快二维沸石纳米片的设计与开发、实现二维沸石纳米片的规模化可控合成与结构调控、充分发挥二维沸石纳米片的双重优势,是实现其工业化应用的必要前提。本文综述了二维沸石纳米材料的研究进展,介绍了二维沸石纳米片的结构与特点,着重讨论了“自上而下”和“自下而上”两种合成策略及其在分子筛膜和催化剂制备方面的潜在应用,阐述了二维沸石纳米片的发展方向和亟待解决的问题。2D zeolite nanosheets simultaneously inherit the special physicochemical properties of 2D nanomaterials and the frame structure and channels of zeolite. Featuring their unique characteristics such as electron confinement, atomic thickness, ultra-high specific surface area, and high percentages of exposed atoms, 2D zeolite nanosheets are considered to have wide application potential in the fields of petrochemical industry, fine chemistry, energy and environment. On the other hand, to realize industrial application and to make full use of the material’s dual advantages, intensive research efforts on the design and development of 2D zeolite nanosheets have been made worldwide in recent years, aiming at large-scale and controllable synthesis and structural regulation. Herein, we review the recent progress in research of 2D zeolite nanosheets, by presenting in this paper a brief introduction of structural characteristics, a detailed summary of the specific preparation methods under the perspectives of two diametrically different synthetic strategies, i.e., top-down and bottom-up ones, as well as a description of the potential applications as zeolite membrane and supported catalysts. The paper ends with a prospective discussion giving our understanding about the challenges and existing problems for the future research.
