Physicochemical Properties of Alumina Supported Silver Catalysts and Their Supports... 

In this chapter, our continued work on the applieation of perovskites for the purification of exhaust gases including NO, C3H5 and CO of motor vehicles was investigated other recent eatalysts for SCR of NO were also diseussed ineluding different mixed oxides, alumina supported silver and copper exchanged mesostruetured alumino-silieate MCM-41. The following conclusions can be made based on the experimental results.

Supported catalysts in which a metal oxide is supported on a different metal oxide find tremendous use in commercial chemical production, petroleum refining, and environmental remediation [7], Table 2.1 lists a number of important industrial reactions that are catalyzed by supported metal oxides. The active phase consists of single metal oxides, metal oxide mixtures, or complex metal oxides. Some supported metal catalysts can, technically, be considered supported metal oxide catalysts if the metal is partially oxidized under reaction conditions, such as alumina-supported silver epoxidation catalysts and palladium-on-stabilized alumina combustion catalysts. Clearly, supported metal oxide compositions are diverse, especially considering that the range of relative amounts of the active phase to the support is large, and that additional metal oxides and modifiers can be introduced. 

The Mild Oxidation of Olefins (MOOs) gathers MOX and ODH reactions of C2-C40lefins to epoxides, aldehydes, and acids or anhydrides (Figure 10.8). Epox-idation of ethylene proceeds on alumina supported silver which, here, is supposed to undergo oxidation to Ag20 (Am = 1.25) during the course of the reaction.
