Research Description

With the rise of societal energy demands, the potential for new fuels from renewable sources that are both readily synthesized and environmentally benign will only increase. The catalytic conversion of carbon dioxide into usable fuels has gained attention, due to the great quantity of CO2 in the atmosphere, as well as that from biomass, both of which contribute to a carbon neutral cycle. Research conducted in the Baber lab focuses on the production of clean fuels using novel catalytic carbide and oxide model systems. Transition metal carbide and oxide surfaces are synthesized, characterized, and optimized for catalytic activity. Structure/reactivity relationships are explored via unique catalyst configurations that are involved in critical reaction steps. The fundamental characterization of atomic-scale active sites and reactions is necessary for understanding reaction pathways, leading to the synthesis and conversion of new fuels and the rational design of the next generation of catalysts that can deliver the desired reactivity.
