Two-dimensional (2D) materials with atom- or few-atoms-thick layers have emerged as building-blocks in the synthesis of the next-generation membrane-based separations. Generally, 2D material-based membranes display high permeation and high selectivity due to their unique structure composed of nanopores and nanochannels with extremely short transport pathways. In this review, the latest advances and ground-breaking research studies on 2D nanosheets for gas separation are highlighted with a focus on the different strategies in synthesizing 2D nanosheets, their assembly into thin membranes and the type of transport mechanism taking place in such membranes.
具有原子级或仅几个原子厚层的二维（2D）材料已成为下一代基于膜的分离合成中的构建模块。一般来说，基于二维材料的膜由于其独特的结构（由具有极短传输路径的纳米孔和纳米通道组成）而表现出高渗透性和高选择性。在这篇综述中，重点介绍了二维纳米片用于气体分离的最新进展和开创性研究，重点关注合成二维纳米片的不同策略、它们组装成薄膜的过程以及此类膜中发生的传输机制类型。
