| My research project in Dr. Scott's laboratory involves the activation of C-H bonds over catalytic zeolites modified with zinc or gallium. These then catalyze the dehydrogenation and aromatization of alkanes, and the selective reduction of nitrogen oxides by hydrocarbons. They are used to convert liquefied petroleum gas, propane/butane into benzene/toluene/xylene. How well these reactions work depends on the dispersion of zinc or gallium in the silicate support. The catalyst is prepared by grafting volatile ZnMe2 or GaMe3 onto the surface to form the catalyst. Given that there is a relationship between the structure and its activity, we will use extended X-ray absorption fine structure spectroscopy, 1H, 13C, and 29Si solid-state NMR, IR, and elemental and gas phase analysis to study alkane activation.
