| dc.description.abstract | Exhaust gases from a wide variety of industrial processes continue to release considerable amounts of CO2 gas into the atmosphere, thereby exacerbating anthropogenic climate change. A new class of porous inorganic-organic hybrid materials referred to as Metal-Organic Frameworks (MOFs) have recently gained attention due to their gas storage and separation capabilities – notably the capture of CO2 present in industrial exhaust gas. In this study, the CO2 adsorption of the MOF MIL-100(Cr) was studied. Five batches of MIL-100(Cr) were synthesized and characterized using three primary material characterization techniques: x-ray diffraction, thermogravimetric analysis, and N2 physisorption. The comparison between the results of these characterization experiments and literature data indicate that the five batches of synthesized material have the same structure as the MIL-100(Cr) material reported in the literature, enabling the samples to be mixed and subsequently used for CO2 adsorption experiments. The CO2 adsorption isotherms revealed that the CO2 adsorption of the MOF increased with pretreatment temperature. A similar trend has been reported in the literature for ethylene adsorption on MIL-100(Cr), which corresponded to the thermally-induced formation of Cr2+ metal sites on the MOF material. IR spectroscopy and quantum chemistry computational simulations can be utilized during future investigations to obtain a molecular-level perspective on why increasing pretreatment temperature enhances CO2 uptake in MIL-100(Cr). | |
