Valorizing Renewable Feedstocks with Sustainable Heterogeneous Catalysis
My research interests lie in leveraging tunable heterogeneous catalytic systems to enable sustainable chemical transformations including the chemical upcycling of waste plastics, and catalytic upgrading of biomass-derived platform molecules. By developing targeted active catalytic sites to enable new chemical transformations and leveraging advanced characterization techniques, my research aims to advance the field of renewable and sustainable chemical production, shifting away from fossil fuel consumption and mitigating the detrimental environmental effects of waste plastics.
The vision of the Rorrer Lab is to combine targeted catalyst characterization and rigorous kinetics at the intersection of model and realistic feedstocks to develop tunable earth abundant materials to valorize complex sustainably-derived feedstocks, enabling a circular carbon economy.
Plastics Depolymerization and Upcycling
Single-use plastics are accumulating in landfills and the natural environment at unsustainable rates. Plastic upcycling is a method of creating valuable products from waste plastics. In my research, I use chemical catalysis to depolymerize waste polyolefins into liquid alkanes that could be used as fuel, or to replace petroleum-derived sources for the synthesis of new plastics.
Upgrading Renewable Platform Molecules Using Tandem Catalysis
Biomass-derived platform molecules such as alcohols and ketones have the potential to provide a renewable alternative to petroleum-derived products. I aim to develop and investigate processes to convert these platform molecules into useful fuels, lubricants, and specialty chemicals.
Fundamentals of C-C, C-O, and C-X Bond Activation
In order to develop selective and active catalysts and catalytic systems to transform sustainable and renewable feedstocks into valuable products, we must develop a fundamental understanding of the underlying mechanisms and kinetics of the processes. Through a combination of catalyst synthesis and characterization, kinetic probing and microkinetic modeling, and in situ characterization, my research aims to develop relationships between catalyst structure and activity to enable selective and active chemistries for plastics depolymerization, biomass upgrading, and other sustainable transformations.
