dc.description.abstract | Germanium-containing, extra-large pore molecular sieve CIT-13 is synthesized without the use of fluoride. After the removal of occluded organics, CIT-13 obtained from fluoride-free preparation shows significant differences from CIT-13 samples prepared in the presence of fluoride. CIT-13 prepared using a fluoride-free method is able to undergo inverse sigma transformation to yield CIT-14 and transforms into a CIT-5-type germanosilicate much faster than Ge-CIT-13 of similar Si/Ge ratios from a fluoride-containing synthesis. A Rietveld-refined structure solution for CIT-14 reveals that this new molecular sieve possesses 12- and 8-membered ring channels. Results from F-19 magic-angle spinning (MAS) and H-1-Si-29 cross-polarized MAS nuclear magnetic resonance spectroscopy reveal that CIT-13 crystallized Without fluoride has germanium siting which is different from CIT-13 synthesized in the presence of fluoride. | - |
