Abstract

A custom designed and constructed three stage ultra-high vacuum apparatus was used to synthesize, characterize, and investigate the activity of model metal/metal oxide catalysts toward reactions of ethanol. The apparatus allows us to synthesize size-selected nanoparticles in-situ, soft land these particles on a clean single crystal surface, use surface science techniques for characterization of the catalyst, investigate electrochemical activity, and re-characterize catalysts without any exposure to atmosphere. Most notably, NbxOy/Pt catalysts were synthesized in-situ, characterized using surface science techniques, investigated using CV for ethanol oxidation, and then characterized again. The ability to characterize catalysts before and after electrochemical reaction without exposure to atmosphere is extremely useful in determining how the electrochemical reaction conditions affect the structural and electronic properties of these catalysts. | 142 pages
