| Abstract: | Anion functionalized strategy has been proposed for the synthesis of macro‐porous resins IRA‐900]An] through the neutral reaction of the basic resin IRA‐900]OH] with the corresponding donors. Combining CO2 adsorption results and FT‐IR, solid‐state 13C NMR characterization as well as quantum chemical calculations, chemical adsorption mechanism was verified and tunable capture of CO2 was realized. Among them, the anion functionalized resin IRA‐900]Triz] exhibits an extremely high adsorption capacity (4.02 mmol g?1 at 25°C, 0.15 bar), outperforming many other good adsorbents. Finally, we discuss the thermostability and recycling stability of IRA‐900]Triz], which shows a great potential in the industrial capture of CO2. © 2017 American Institute of Chemical Engineers AIChE J, 63: 3008–3015, 2017 |
