An ionic liquid 1-butyl-3-methylimidazolium hydroxide ([Bmim]OH) was grafted on silica gel by post-grafting method. Such grafted ionic liquids (GILs) which were verified by means of FTIR, element analysis N2adsorption-desorption and TG could be used as highly effective heterogeneous catalysts toward propylene carbonate synthesis through cycloaddition of carbon dioxide with propylene oxide under solventless and mild conditions.

An ionic liquid 1- (triethoxysilyl) propyl-3-methylimidazolium hydroxide ([Smim]OH) was grafted on three kinds of mesoporous hydrophobic silica gel by means of post-grafting under mild conditions. The catalysts were [Smim]OH/SiO2-MTES (methyltriethoxysilane), [Smim]OH/SiO2-TMCS (trimethylchlorosilane), [Smim]OH/SiO2-CPTEO (triethoxysilyl propyl chloride). Such grafted ionic liquids (GILs), which were characterized by means of FTIR and N2 adsorption-desorption could be used as effective heterogeneous catalysts toward propylene carbonate synthesis through cycloaddition of carbon dioxide with propylene oxide under solventless and mild conditions.

Poly Ionic Liquid

The design and synthesis of solid sorbents for effective carbon dioxide adsorption are essential for practical applications regarding carbon emissions. Herein, we report the synthesis of composite materials consisting of amine-functionalized imidazolium-type poly(ionic liquid) (PIL) and metal organic frameworks (MOFs) through complexation of amino groups and metal ions. The carbon dioxide adsorption behavior of the synthesized composite materials was evaluated using the temperature-programmed desorption (TPD) technique. Benefiting from the large surface area of metal organic frameworks and high carbon dioxide diffusivity in ionic liquid moieties, the carbon dioxide adsorption capacity of the synthesized composite material reached 19.5 cm3·g−1, which is much higher than that of pristine metal organic frameworks (3.1 cm3·g−1) under carbon dioxide partial pressure of 0.2 bar at 25 °C. The results demonstrate that the combination of functionalized poly(ionic liquid) with metal organic frameworks can be a promising solid sorbent for carbon dioxide adsorption.

A two-step swelling method was used for preparing porous poly(ionic liquid)s based on the copolymer of 1-allyl-3-methylimidazolium tetrafluoroborate and acrylonitrile P([AMIM]BF4-AN), the copolymer of 1-allyl-3-methylimidazolium hexafluorophosphate and acrylonitrile P([AMIM]PF6-AN), and poly(vinylbenzyl trimethylammonium) tetrafluoroborate P[VBTMA]BF4. The characteristics of the polymers were assessed via FT-IR spectroscopy, scanning electron microscopy (SEM) and CO2 adsorption. The results indicated that the seed-swelling method was more effective in improving the CO2 adsorption capacity of imidazolium-based P([AMIM]BF4-AN) containing the [BF4]− anion. Exchanging [BF4]− for [PF6]− in the imidazolium-based poly(ionic liquid) led to almost the same CO2 adsorption as exhibited by the corresponding non-swelling copolymer. Moreover, the CO2 adsorption capacity of ammonium-based P[VBTMA]BF4 when treated by the seed-swelling method decreased considerably.
