多孔液体在气体捕集与分离领域的应用

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.
