摘要
二维纳米材料作为一种新兴材料,具有原子级的厚度、高纵横比、优良的机械性和化学稳定性,且可大规模制备,被认为是膜基气体分离领域最具有前途的候选材料.2D纳米材料的缺陷为2D纳米材料在膜分离领域的应用开辟了新的道路,为膜分离提供了一种简单而高效的增强膜分离性能的方法.然而,利用缺陷工程来定制气体分离膜的微观结构和提高分离性能仍处于起始阶段.因此,本综述旨在为缺陷2D纳米材料基膜提供指导.本文首先讨论2D纳米材料基复合膜缺陷工程的最新进展.其次,讨论了缺陷2D纳米材料的合成策略,重点讨论缺陷2D纳米材料基复合膜在CO_(2)捕获领域的应用.最后,概括总结了新出现的挑战和未来前景.
2D nanomaterials,as an emerging material with atomic-level thickness,high aspect ratio,excellent mechanical and chemical stability,and large-scale preparation,are considered to be the most promising candidates in the field of membrane-based gas separation.The defects of 2D nanomaterials have opened a new path for the application of 2D nanomaterials in membrane separation,providing a simple and efficient enhancement of membrane separation performance.However,the use of defect engineering to tailor the microstructure of gas separation membranes and to improve separation performance is still in its infancy.Therefore,this review aims to provide guidance for defective 2D nanomaterial-based membranes.This paper first discusses recent advances in defect engineering of 2D nanomaterial-based composite membranes.Secondly,strategies for synthesizing defective 2D nanomaterials are discussed,focusing on the application of defective 2D nanomaterial-based composite membranes in CO_(2) capture.Finally,emerging challenges and future prospects are summarized.
