摘要
多孔液体是指具有永久性孔隙的液体材料,其将多孔固体的有序规整孔道和液体的流动性等诸多优点相结合,在气体捕集与分离领域表现出巨大的应用潜力,成为新的研究热点。本文首先简单阐述了多孔液体的概念及分类,并总结了多孔液体形成的必要条件;然后分别详细综述了三类多孔液体的合成进展,并阐述了多孔液体在气体捕集与分离方面的应用,着重介绍了近五年的研究进展;最后对其现存的挑战及未来展望进行了总结。
Porous liquids(PLs),an emerging class of liquid materials with permanent porosity and good fluidity,have shown great potential in gas capture and separation.As a result,PLs used as gas capture materials have become a new research hot spot.In the present paper,the concept of PLs is firstly introduced in a nutshell.Then,the composition characteristics and the necessary conditions for constructing PLs are analyzed.Next,the synthesis progress of these three types of PLs are reviewed in detail,and their gas capture and separation performance are analyzed,especially after 2015.Lastly,the existing challenges of porous liquids and their outlooks of synthetic methods and applications in gas capture are outlined and presented.
