Building and characterization of catalysts on single crystal surfaces

Abstract

The components of complex catalyst systems include transition metals, oxides, alkali metal or halogen additives and strongly chemisorbed sulfur or carbonaceous species. Modern surface science techniques identified the chemical and structural roles of these ingredients when used in combination with catalytic reaction rate studies. Using metal single crystal substrates, catalyst components have been deposited from the vapor phase and the complex catalyst system could be built this way. The Pt-Re-S, Rh-TiO2, and Mo-Co-S systems are reviewed and the requirements for the proper surface structure and composition to obtain high reaction rates and selectivities are discussed.
