Utilization of carbon dioxide (CO2) has become an important global issue due to significant and continuous rise in atmospheric CO2 concentrations. To find a potential solution, two types of mesoporous materials, MCM-41 and MCM-48, were synthesized and
impregnated with 30, 50 and 70 wt% of polyethyleneimine (PEI) in methanol to evaluate the performance of the materials in
terms of CO2 adsorption. The materials were characterized by XRD, TGA, FTIR, TEM, SEM, N2-physisorption and BET techniques. All the PEI-loaded materials exhibited substantially higher reversible CO2 adsorption-desorption behaviors with >99% recovery. The above study proved that MCM-48 is a better material as compared to
MCM-41 for loading of PEI. The material with 50 wt% loading of PEI on MCM-48, showed maximum adsorption of 248 mg/g-PEI at
80 °C which is about 30 times higher than that of MCM-48 and about 2.3 times that of pure PEI. 相似文献
