Materials Chemistry and Heterogeneous Catalysis

A project on the molecular design and synthesis of solid-state materials is based on development of chemical routes to complex, 3-dimensional networks via molecular-level control. Primary targets are multi-component, oxygen-containing materials which are fabricated from tailored, oxygen-rich precursor molecules. This approach has been used to obtain new catalysts for selective hydrocarbon oxidations. Related molecular precursors are used to introduce isolated catalytic sites onto the surface of an oxide support. Advantages to the latter method include the increased potential for molecular-level control over structure, the generation of site-isolated catalytic centers, and the availability of good spectroscopic models for the catalytic site. Further efforts employ chemical modifications of the catalyst support surface to enhance binding and activation of substrates, and release of products.
