Surface science has been increasingly utilized in recent years to explore the molecular details of heterogeneous catalytic processes. A large number of techniques have been developed which determine the atomic surface structure, the composition, and oxidation states in the surface monolayer. Correlations of studies of catalytic reaction rates and product distributions with atomic scale surface properties revealed many important ingredients of surface reactivity. The structure of the catalytic surface markedly influences the surface chemical bonds of adsorbed molecules. Additives which are often electron donors (alkali metals) or electron acceptors (halogens) change the oxidation state of surface atoms, block sites, or change the surface structure and markedly influence the surface reactivity. The catalyzed reactions of carbonaceous deposits and water vapor are discussed along with the possible importance of trace metals and high-surface-area alumina silicates in atmospheric chemistry.
