About Me
I am from Louisville, KY, and I received my B.S. in Chemical Engineering (cum laude) from the University of Virginia in 2012. I started at Purdue in the fall semester in 2012, where I was a Ross Fellow (2012-2013). I was a Rodman Scholar at the University of Virginia, and was awarded third place in the University's Undergraduate Research and Design Symposium (URDS) for a presentation of my independent thesis research entitled "Life Cycle Assessment of Energy Production from Algae: Triclosan from Wastewater." My thesis was titled "Life-cycle assessment of energy production from algae: removal of emerging contaminants from wastewater" and included my science, technology, and society thesis entitled "Policy factors affecting biofuel feedstock choice in the U.S." I was also a member of a five-person capstone project team that produced a second technical thesis entitled "The growth, extraction, and cracking of algae from botryococcus braunii for biofuel production." My hobbies include running, cycling, and tennis.
Project Description (high-level)
I synthesize aluminum-free Lewis Acid zeolites for use in various reaction studies. These materials are different from traditional zeolites promoted with transition metals in that they do not have a mix of Bronsted and Lewis acid sites, leading to differences in catalytic rates and product selectivities. I make these materials "from scratch," meaning they are free of impurities. I perform several characterization tests to completely identify what the materials are prior to testing them for the reaction(s) I study. Additionally, I've built a complete reactor setup from scratch for catalyst testing with direct injection to a gas chromatograph, which allows me to determine my reaction product distribution without any products condensing and reacting in the liquid phase.
Project Description (detailed)
I am studying metallosilicate zeolites as catalysts for various applications. This project involves synthesis of aluminum-free zeolite structures with various heteroatoms including zinc, tin, titanium, and others. Various characterization techniques are required to certify the success of each synthesis, including XRD, diffuse-reflectance UV-VIS (DRUV), NMR, micropore volume and surface area measurements via nitrogen physisorption, acid site titration with in situ IR spectroscopy and various probe molecules, atomic absorption (AA), and testing via probe reactions. Zeolites with isolated framework metal atoms have not been tested as catalysts for many industrial reactions as they require complicated and lengthy synthesis procedures when synthesized via traditional hydrothermal routes. To address this issue, I will also be testing zeolites synthesized by dealuminating industrially available catalysts followed by "healing in" various metal atoms to the zeolitic framework. I am also testing amorphous silica promoted with "single-site" transition metals via the strong electrostatic attraction (SEA) technique for comparison to the crystalline materials with isolated metal atoms in siliceous frameworks to determine the benefit of size-selectivity afforded by using zeolites.
