CO2 adsorption and characterization of tailor-made metal-organic frameworks


In this work, the 𝐶𝑂2adsorption capacityof chemically interesting metal-organic frameworks (MOFs) have been investigated. The MOFs have been characterized using standard inorganic/organic characterization tools such as pXRD, TGA, liquidand solid state NMR, SEM-EDS, static anddynamic gas adsorption.Potentially strong adsorption sites on the Pt–Zr interface was investigated by the use of TAP. The isosteric heat of adsorption have been estimated for UiO –67 as a function of pretreatment.A comparison of the isosteric heat of adsorption determined by the use of static and dynamic gas adsorption studies have been made.A two-step adsorption mechanismin the N2adsorption isotherm was observed for UiO –67 in the low pressure regime (𝑝𝑝0<0.005). The observed adsorption isothermshow resemblance to that of MOF –808, however occurring at a much lower pressure.UiO –67 and UiO –67 type MOFs have been investigated by the use of ss –NMR. A major effort was made towards the assignment of the peaks in therecorded1H and 13C spectrum of UiO –67. The work was leading to the hopeful elucidation of adsorption sites and adsorption orientations, however due to time constraint only the groundworkhave been performed.
