Heterogeneous Catalysis
We combine the preparation of controlled nanomaterials with experimental kinetics studies and in situ and operando characterization of surface species at reaction conditions to gain fundamental knowledge on reaction pathways, mechanism, and catalyst requirements.
We use the above insights into active sites and intermediate species to guide the preparation of novel and/or improved catalytic materials that are more active and selective for the conversion of renewable biomass derived feedstocks, abundant natural gas components, and for environmental applications.
