| Summary: | The primary focus of this research was to investigate novel solid acid and solid base systems by multinuclear MAS NMR, in order to provide a better understanding of the rich chemistry observed for these systems. As part of this effort the first modern spectroscopic study of the solid phosphoric acid catalyst system was reported. 31P and 29Si MAS NMR were used to characterize the crystalline support and the dynamics of the oligomerized acid of the catalyst. The nature and strength of the acid function of the catalyst was investigated by use of probe molecules. Probe molecules studies involving pyridine and acetone were used to unambiguously localize the chemisorption site of the catalyst via a double cross polarization MAS NMR experiment. Two novel intermediates were generated and characterized during the decomposition of chlorinated volatile organic compounds over a cation exchanged zeolite. A survey of the alkali metal peroxides and superoxides was accomplished by means of 7Li, 23Na, 39K, 87Rb. and 133CS MAS NMR in an attempt to further the understanding of these basic and oxidizing systems. |
