Catalysis: Reactivity and Structure (CRS) Group
This program pursues an improved understanding of chemical catalysis for advanced fuels synthesis and energy conversion processes by elucidating catalytically important properties of well-defined surfaces, powders and nanostructures. We study and manipulate in a systematic way a series of multifunctional catalysts which contain metal-oxide, metal-carbide or metal-sulfide interfaces. Our comprehensive research program examines the effects of size, morphology and chemical environment, providing a truly atomistic view for explaining/predicting catalytic activity.
Complexities stemming from the inherent multi-component aspects of heterogeneous catalysis are explored using both ultra-high-vacuum surface science investigations of well-defined model systems, and powder diffraction and x-ray absorption studies of "real-world" systems. We bring distinct methods to common reaction themes in fuel synthesis such as desulfurization, hydrogen production and oxygenate synthesis.
We develop and apply new approaches for the in-situ characterization of heterogeneous catalysts using facilities available at the National Synchrotron Light Source for X-ray diffraction, X-ray absorption and photoemission. Quantum-chemical computation plays an essential role for basic understanding of catalytic reactions and interpretation of experimental results.
We prepare nanostructured materials for catalysis, focusing on the characterization and reactivity of metal nanostructures. The goal is to identify and characterize the catalytically active sites of supported nanocatalysts and to investigate the influence of particle size, morphology and support on nanostructure reactivity.
