Surface Chemistry and Catalysis Group

Surface Chemistry and Catalysis Group

The Surface Chemistry and Heterogeneous Catalysis Group at Oak Ridge National Laboratory conducts research into surface chemistry and fundamentals of catalytic reactions at metal surfaces, metal oxide surfaces and supported metal catalysts. Two approaches include "surface science" studies of model surfaces and  "catalytic" studies of high surface area, novel materials. A major portion of the group's basic research is aimed at research into the Fundamentals of Catalysis and Chemical Transformations sponsored by the DOE's Office of Science, Basic Energy Sciences, Chemical Sciences, Geosciences, and Biosciences Division.

Controlling Reaction Selectivity through the Surface Termination of Perovskite Catalysts

Although perovskites have been widely used in catalysis, tuning of their surface termination to control reaction selectivity has not been well established. In this study, we employed multiple surface...

Acid–Base Reactivity of Perovskite Catalysts Probed via Conversion of 2-Propanol over Titanates and Zirconates

Although perovskite catalysts are well-known for their excellent redox property, their acid–base reactivity remains largely unknown. To explore the potential of perovskites in acid–base catalysis, we...

Selective conversion of bio-derived ethanol to renewable BTX over Ga-ZSM-5

Selective conversion of bio-derived ethanol to benzene, toluene and xylenes (BTX) is desirable for producing renewable BTX. In this work, we show that addition of Ga to H-ZSM-5 leads to a two-fold...

Research Areas

Research areas include: the surface chemistry of binary oxide surfaces and reactions of oxygenates on oxide surfaces; the synergistic effects of acidity, basicity, reducibility and surface structure of oxides upon the surface chemistry, reactivity and selectivity of oxygenates over both model surfaces and nanocrystals; cooperative catalysis of hierarchically structured metal clusters and nanoparticles supported on oxides; electrocatalytic reactions and redox processes in electrochemical surfaces; acid gases interaction with oxide nanocrystals; and photocatalysis over  low dimensional materials.
