Abstract

In this work, a porous organic polymer (POP) exhibiting abundant N species and rich mesopores was synthesized by solvothermal copolymerization of divinylbenzene (DVB) and 1-vinylimidazole (VI) without the use of any templates. The synthesized POP, abbreviated as P (DVB-VI), was used as the support for pentaethylenehexamine (PEHA) impregnation to prepare solid adsorbents for CO₂ capture. The porous and chemical structures of prepared samples were characterized by elemental analysis, N₂ adsorption, electron microscopy, infrared spectra, and thermogravimetric analysis. The CO₂ capture performance of prepared samples was also systematically investigated by measuring the CO₂ adsorption capacities and CO₂/N₂ selectivities, and the effect of moisture on CO₂ adsorption and recyclability of adsorbents was examined. It was found that PEHA-impregnated P (DVB-VI) adsorbents displayed CO₂ capacities of as high as 4.56 mmol/g at 75 °C and atmospheric pressure, together with excellent CO₂/N₂ selectivities and good recycling stability.
