MOFs-based porous liquids:Preparation and application in CO2 adsorption and separation
Porous Liquids(PLs),novel liquid materials that combine the permanent porosity of porous solid materials and liquid mobility,demonstrate great application potential in the fields such as gas adsorption and separation as well as catalysis.Metal framework materials(MOFs)are expected to be one of the best candidates for constructing PLs porous substrates due to their high specific surface area,thermal and chemical stability,unique structure,and simple preparation.In recent years,studies on MOF(ZIF-8,ZIF-67,UiO-66,etc)-based porous liquids have been reported one after another.Herein,the classification of porous liquids were introduced,followed by summarization on the preparation of MOFs-based porous liquids and their applications in recent years.Finally,the existing challenges and future development directions in preparation of MOFs-based porous liquids were discussed.
