Precise and ultrafast ion sieving is highly desirable for many applications in environment-, energy-, and resource-related fields. The development of a permselective lamellar membrane constructed from parallel stacked two-dimensional (2D) nanosheets opened a new avenue for the development of next-generation separation technology because of the unprecedented diversity of the designable interior nanochannels. In this Review, we first discuss the construction of homo- and heterolaminar nanoarchitectures from the starting materials to the emerging preparation strategies. We then explore the property-performance relationships, with a particular emphasis on the effects of physical structural features, chemical properties, and external environment stimuli on ion transport behavior under nanoconfinement. We also present existing and potential applications of 2D membranes in desalination, ion recovery, and energy conversion. Finally, we discuss the challenges and outline research directions in this promising field.
精确且超快的离子筛分对于环境、能源和资源相关领域的许多应用来说是非常理想的。由平行堆叠的二维（2D）纳米片构建的选择性渗透层状膜的发展，为下一代分离技术的发展开辟了一条新途径，这是因为可设计的内部纳米通道具有前所未有的多样性。在本综述中，我们首先讨论从起始材料到新兴制备策略的同层和异层纳米结构的构建。然后，我们探索性能关系，特别强调物理结构特征、化学性质和外部环境刺激对纳米限域下离子传输行为的影响。我们还介绍了二维膜在海水淡化、离子回收和能量转换方面的现有和潜在应用。最后，我们讨论了这一有前景领域中的挑战并概述了研究方向。
