dc.description.abstractTwo mechanisms of increasing the water and structural stability of metal-organic frameworks (MOFs) were investigated. Two carboxylate MOFs, Mg-MOF-74 and HKUST-1, were post-synthetically modified with silica to increase structural stability while retaining the originally high zero-loading heats of adsorption, 65.4 kJ/mol and 32.2 kJ/mol, respectively. The modified materials were characterized by NMR, IR, SEM/EDX, PXRD, TGA, and adsorption of CO2 and N2. The silicated HKUST-1 showed remarkably high water stability, whereas the silicated Mg-MOF-74 did not. A second approach to stability was investigated using a novel phosphonate ligand, 2,7-bis(ethylphosphono)fluorene, yielding hollow microspheres upon hydrothermal reaction with cobalt (II) nitrate. The microspheres were thermally stable to 450°C, and were stable to sonication in water. The mechanism of formation, structure and chemical stability were investigated and will be discussed.en_US

The University of Calgary, located in the heart of Southern Alberta, both acknowledges and pays tribute to the traditional territories of the peoples of Treaty 7, which include the Blackfoot Confederacy (comprised of the Siksika, the Piikani, and the Kainai First Nations), the Tsuut’ina First Nation, and the Stoney Nakoda (including Chiniki, Bearspaw, and Goodstoney First Nations). The City of Calgary is also home to the Métis Nation of Alberta (Districts 5 and 6).

The University of Calgary is situated on land Northwest of where the Bow River meets the Elbow River, a site traditionally known as Moh’kins’tsis to the Blackfoot, Wîchîspa to the Stoney Nakoda, and Guts’ists’i to the Tsuut’ina. On this land and in this place we strive to learn together, walk together, and grow together “in a good way.”
