Summary:Porous liquids are a novel class of porous materials that integrate the permanent porosity of solids with the fluidity of liquids. By rational combination of porous solids and liquid solvents, it becomes possible to design and create porous liquids, which hold significant potential in gas capture and separation. Since the concept was initially proposed in 2007, research on the preparation of porous liquids has advanced rapidly. The rational fabrication of porous liquids is presented and their physicochemical parameters are summarized. Additionally, the mass transfer-reaction mechanisms and the applications of porous liquids in gas sorption and separation are discussed. Finally, the existing challenges are highlighted, and an appropriate design strategy direction for the transition of porous liquids from the laboratory to practical application is proposed. Porous liquids are a novel class of porous materials that integrate the permanent porosity of solids with the fluidity of liquids.
