Catalytic materials are central to most industrial processes. We develop novel designs and syntheses of catalysts, adsorbents, and other functional materials especially for the purpose of more sustainable routes to important chemicals and fuels. We frequently collaborate with industry and national laboratories on such projects. We typically synthesize materials by modifying existing particle surfaces with organic functionalities (e.g. amines or carboxylates), inorganic complexes (e.g. Mn triazacyclononane, Ta calixarenes) or we build up additional, ultra-thin oxide layers. These groups are intended to control isolated or cooperative active sites consisting of acids, bases, redox groups, metals, and designed cavities in ways that can be difficult to engineer with traditional homogeneous or heterogeneous catalysts. The active sites on these new materials are also functional models for spectroscopy and simulation for the development of improved structure-function relationships. It is our guiding hypothesis that increasing control over - and diversity of - the active sites available for heterogeneous catalysts promises to yield new, more selective, and better understood chemical transformations.
We have developed supported metal nanoparticle catalysts, oxide catalysts, immobilized molecular catalysts, and nanocavity catalysts. Chemical transformations currently being explored include selective oxidation, NO reduction, hydrotreating (hydrodenitrogenation and hydrodeoxygenation), photocatalysis, CO2 photoreduction, carbon capture and conversion, aldol condensation and related reactions, sugar and other biomass conversions, dehydration, decarboxylation, and selective adsorption of butanol and other molecules. An overarching long-term goal is to be able to design systems of active sites on a single surface capable of complex, efficient transformations of challenging molecules, in ways that mimic the connectivity of biological reaction pathways.
