Aaron Appel is a chemist and Team Leader for Molecular Catalysis in the Catalysis Science Group. His research focuses on designing catalysts and electrocatalysts for interconversion of energy and fuels, as well as electrochemically switchable sorbents for CO2. His research has two aspects: thermodynamic studies of discreet bond forming and bond breaking events, and the design and testing of complexes and catalysts based on the resulting thermodynamic data. Aaron has applied this approach to the production and utilization of hydrogen, to the reduction of carbon dioxide to liquid fuels, and to transformations of addition small molecules for energy storage. Aaron holds a PhD in Chemistry from the University of Colorado Boulder and a BS in Chemistry from Washington State University.
