Research progress on porous liquids for CO2 capture and utilization
In order to achieve the national"dual carbon goal"as soon as possible and implement the important measures of green,low-carbon and sustainable development in the chemical industry,adsorption/absorption coupling is expected to become a green and revolutionary separation technology for gas separation,and the key is to develop high-performance adsorption materials.Porous liquids,a kind of liquid material with permanent pores,combine the advantages of liquid absorbents(such as easy pipeline transportation,efficient mass and heat transfer)with those of solid adsorbents(such as high specific surface area and porosity),and are expected to be a new generation of green,transformative media for CO2 capture.In this review,the development of porous liquids was briefly introduced.The applications of porous liquids in CO2 adsorption/absorption,membrane separation,and catalytic conversion were then discussed in detail,followed by summarization on the performances,advantages and disadvantages of porous liquids.Finally,the current challenges and future development trends of porous liquids were prospected.
