Abstract

The interaction between palladium and ceria, both supported on alumina, has been explored in the context of the reverse water-gas shift reaction. Specific rates of reaction were greater over catalysts containing ceria. The reaction kinetics were consistent with reaction between dissociatively adsorbed hydrogen and dissociatively adsorbed carbon dioxide, a reaction which is accelerated by migration of adsorbed oxygen across the metal surface to the ceria surface.
