Abstract | Covalently tethered CO2 adsorbents are synthesized by acid catalyzed ring-opening polymerization of aziridine on the basal planes of three-dimensional hydroxylated graphene (HG). The resulting materials possess high surface areas, strong covalent bonds between polyethyleneimine (PEI) and graphene, and high thermal conductivity. The HG-PEI nanocomposites exhibit high amine loading (more than 10.03 mmol N g(-1)), high adsorption capacity (up to 4.13 mmol CO2 g(-1) in simulated ambient air under 1 atm of dry CO2) as well as good stability both at low (100 degrees C) and high desorption temperatures (135 degrees C), which allows the overall CO2 capture process to be promising and sustainable. |
