Abstract

Two-dimensional porous nanosheets such as metal-organic frameworks, covalent organic frameworks, fluorides of light lanthanide, and perforated graphene oxide are a class of nanomaterials with sheet-like morphologies and defined pore structures. Due to their porous structure and large lateral sizes, these materials exhibit excellent molecular transport properties in separation processes. This review focuses on the pore formation strategies for two-dimensional porous nanosheets and applications of these nanosheets and their constructed membranes in gas separation processes and separation processes applicable to water treatment and the humidity control of gas permeation. A brief discussion of challenges and future developments of separation applications with two-dimensional porous nanosheets and their constructed membranes is included in this review.

基于二维多孔纳米片的先进膜分离技术

二维多孔纳米片（如金属有机框架、共价有机框架、轻镧系元素氟化物和穿孔氧化石墨烯）是一类具有片状形态和明确孔隙结构的纳米材料。由于其多孔结构和较大的横向尺寸，这些材料在分离过程中表现出优异的分子传输特性。本综述重点介绍二维多孔纳米片的孔隙形成策略，以及这些纳米片及其构建的膜在气体分离过程和适用于水处理及气体渗透湿度控制的分离过程中的应用。本综述还简要讨论了使用二维多孔纳米片及其构建的膜进行分离应用所面临的挑战和未来发展。
