Description:: Molybdenum oxides and sulfides are earth-abundant materials known to catalyze a wide array of reactions, including dehydrogenation, hydrotreating, and higher alcohols synthesis. In particular, alkane and alcohol dehydrogenation are of interest given recent shifts in the energy landscape away from traditional petroleum feedstocks and towards natural gas and renewable energy...

Description:: Supported vanadium oxide materials have been extensively studied for alkane oxidative dehydrogenation (ODH) reactions due to their high activity and selectivity. The catalytic activity of supported VOx materials is influenced by the surface coverage of VOx sites and hence the distribution of V=O, V-O-V, and V-O-S (S, support) bonds. The...

Description:: Supported metal oxides are an important class of catalysts for chemical synthesis and manufacturing, particularly for selective oxidation reactions. This dissertation seeks to understand broad relationships among families of silica-supported Group 4 and 5 metal oxide catalysts for the synthesis of epoxides with hydrogen peroxide (H2O2) and to further extend...
