"Development of Electrocatalytic Materials Guided by Computational Chemistry: Fuel Cells and CO2 Electroreduction"

Michael Janik, Associate Professor, Department of Chemical Engineering, Penn State University

Abstract:
Our group applies computational chemistry techniques to a range of catalyst and materials design challenges in energy technology. This presentation will concentrate on our work in electrocatalysis.Electrocatalysts are an essential component of fuel cells, electrolyzers, and some battery technologies. The development of composition-structure-functional relationships guides rational design of electrocatalytic materials. Quantum mechanics based computational techniques, such as density functional theory methods, are a useful tool in guiding catalyst design. Density functional theory (DFT) methods are widely used to evaluate surface catalytic reaction mechanisms and to predict the relative performance of various catalyst formulations or structures. Translation of DFT approaches to the electrocatalytic environment requires additional methodological choices due to additional complexities offered by the electrified catalyst-electrolyte interface. This talk will provide an overview of the challenges to atomistic modeling of electrochemical interfaces and describe the various DFT approaches used to model electrocatalytic systems. The use of DFT to determine electrocatalytic reaction mechanisms and guide the design of catalytic materials will be discussed using examples from our group’s research; hydrogen fuel cells, borohydride fuel cells, and carbon dioxide reduction to fuels.
