微孔膜作为选择性屏障，在工业气体分离和水净化中发挥着重要作用。这种膜的渗透性与其厚度成反比。厚度为一到几个原子或单体单元的合成二维材料（2DM）是开发分离膜的理想选择。在此，介绍了用于气体和离子分离以及水淡化的 2DM 的设计、合成、加工和应用方面的突破性进展。该报告描述了 2DM 的合成、结构和机械性能。还讨论了将 2DM 加工成选择性渗透膜的既定方法，并讨论了分离机制及其性能。总结了开发下一代分离膜所需解决的当前挑战和新兴研究方向。
Microporous membranes act as selective barriers and play an important role in industrial gas separation and water purification. The permeability of such membranes is inversely proportional to their thickness. Synthetic two‐dimensional materials (2DMs), with a thickness of one to a few atoms or monomer units are ideal candidates for developing separation membranes. Here, groundbreaking advances in the design, synthesis, processing, and application of 2DMs for gas and ion separations, as well as water desalination are presented. This report describes the syntheses, structures, and mechanical properties of 2DMs. The established methods for processing 2DMs into selective permeation membranes are also discussed and the separation mechanism and their performances addressed. Current challenges and emerging research directions, which need to be addressed for developing next‐generation separation membranes, are summarized.
