Abstract
Carbon dioxide (CO2) adsorption on a standard metal-organic framework MIL-101 and a pentaethylenehexamine modified MIL-101 (PEHA-MIL-101) are investigated and compared in this study. The adsorbent samples were characterized by XRD, FT-IR and nitrogen adsorption-desorption isotherms analysis. CO2 adsorption capacity was measured by a volumetric method. MIL-101 and PEHA-MIL-101 exhibited CO2 adsorption capacities of 0.85 and 1.3 mmolCo2/gadsorbent at 10 bar and 298 K, respectively. It is observed that CO2 adsorption capacity was fairly improved about 50% after amine modification.
