Masel, Richard I. Luebbers, Matthew T. 2015-09-25T20:44:02Z 2015-09-25T20:44:02Z 10000-01-01 2010 2010 In the final experimental section, the IGC methodology was applied to a commercially available MOF, ZIF-8, with greatly different geometric and chemical properties from the other MOFs. A molecular-sieving effect was observed preventing the adsorption of branched-alkanes, aromatics, and heavily halogenated compounds. Hydrogen-bonding interactions were found to be important for the adsorption of alcohols and amines. However, the adsorption of hydrogen-bond bases was found to be greatly lessened from that of the other MOFs. Thermodynamics of adsorption for the organic compounds studied were calculated to be significantly reduced from IRMOF-1 and the polarizability was used to calculate the specific component of free energy. The specific component of the free energy was found to correlate well to the dipole moment of the adsorbed species. In addition, significant enhancement was seen in the adsorption of ethylene and propylene over their respective alkanes and this was attributed to a strong interaction between the pi-electrons present in the alkene with the framework structure.
