Ionic porous organic polymers for CO2 capture and conversion

The predominant greenhouse gas CO2 is the major contributor to the global warming. Very recently, ionic porous organic polymers have been taken as a kind of promising candidate material for addressing the CO2 capture and conversion issue. Compared to most neutral porous materials, ionic porous organic polymers exhibit excellent CO2 capture capacity and the ability to convert into cyclic carbonates via reaction with epoxides, owing to the existence of ionic sites in the porous structure. In addition, the counterions can be readily exchanged for tuning the uptake capacity and catalytic performance, which is another advantage for design and synthesis of ionic porous organic polymers. In this short review, we will present recent progress on employing ionic porous organic polymers for the CO2 capture and subsequent conversion.
