Our group investigates reactions at solid surfaces for renewable and sustainable energy applications. We are particularly focused on interfacial chemistry important in the conversion of biomass to fuels and chemicals. Biomass-derived carbohydrates and lipids contain a high degree of oxygenate functionality, and it is a major challenge to develop new catalysts capable of selective conversions of the oxygenates to useful fuel and chemical products. A major focus of our group is to design such catalysts based on a molecular-scale understanding of the oxygenate-catalyst interaction.
Our efforts to research various applications are united by a common theme: a variety of experimental and computational tools are employed to obtain a detailed understanding of chemical and physical phenomena at solid surfaces. Having this understanding in hand allows us to design improved catalysts that we can screen under realistic conditions in chemical reactors.
Our research focuses on the following main areas:
- Surface reactivity and catalyst design for conversion of biomass-derived oxygenates to chemicals
- Model studies of electrocatalytic interfaces
- Designing artificial “binding pockets” on metal catalysts
- Catalysts for selective deoxygenation biomass pyrolysis oil
- Fundamental investigations metal – metal oxide – organic interfaces
