Many industrial processes use catalysts that contain metal oxides either as the catalyst or as the support for expensive metal catalysts such as platinum or palladium. Since a large surface area normally means better catalytic efficiency, thermal decomposition of a precursor solid is often used to prepare high surface area metal oxides for the manufacture of these catalysts. We use thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), and Evolved Gas Analysis- Fourier Analysis Infrared Spectroscopy (EGA-FTIR) to investigate the thermal decomposition pathways of possible precursors for generating metal oxide catalysts. The goals of this project are to establish the decomposition pathways and Arrhenius parameters for the decomposition process so that the conditions needed to form the catalyst can be established. Once the metal oxide is formed, it is characterized using ATR-FTIR, x-ray diffraction, scanning electron microscopy and BET surface area measurements. Pyridine adsorption and dehydration/ dehydrogenation for the thermal decomposition of 2-propanol is used to establish the acid – base and redox properties of the catalyst.
The chemical shift of the OH proton is highly dependent on the solution environment. We are investigating the chemical shift of small alcohol molecules in the vapor phase and in very dilute solutions in an attempt to learn about the hydrogen bonding in these systems. Variable temperature NMR is the instrument of choice. High level DFT calculations (DFT-6-311++G (3df,3pd) calculations on the alcohol cluster species are also done to provide additional information about these systems.
