"At an early age, if I did not understand why something happened or how something worked I would spend as much time as possible until I could at least mildly comprehend what was going on. I was easily able to determine that a research position was the right fit for me after a few semesters in college. During my sophomore year I attended the senior banquet for chemical engineers as a volunteer for the American Institute of Chemical Engineers (AIChE) and Dr. Jason Weaver was the keynote speaker. Even though the topic of his talk was slightly different from what I ended up working with, I still wanted to get involved so I approached him after he finished. I have been working in his lab for a little over 2 years now."

Research Description

CO/NO Oxidation On Pd Oxide Thin Films

My research project will focus on characterizing the oxidation of CO/NO on crystalline Pd oxide thin films as well as the concurrent structural changes that occur as the oxide surfaces are reduced. Motivation for this research comes largely from observations that the formation of ultrathin metal-oxide films dramatically alters the catalytic performance of metals in commercial applications of oxidation catalysis, such as the catalytic combustion of natural gas and exhaust gas remediation in automobiles. In Dr. Weaver’s group, we generate Pd oxide thin films in the well-controlled UHV environment by oxidizing a metallic Pd surface using a beam of plasma-generated oxygen atoms. By also applying spectroscopic measurements to obtain information about the reaction kinetics and the evolution of binding sites, we aim to develop mechanistic models of CO/NO oxidation on Pd oxides that account for changes in catalyst structure during reaction.
