A CO2 adsorbent with high adsorption capacity and high selectivity was prepared based on a novel "molecular basket" concept consisting of mesoporous molecular sieve of MCM-41 type and an immobilized branched polymer with CO2-capturing sites. The novel CO2 "molecular basket" adsorbent was characterized by X-ray powder diffraction (XRD), N2 adsorption/desorption and CO2 adsorption/desorption measurement. The "molecular basket" adsorbent can selectively capture CO2 in a gas mixture and was also applied in the separation of CO2 from simulated flue gas and boiler flue gas.
