Catalysis by Unique Metal Ion Structures in Solid Matrices

Atomically dispersed metal cations and small polyatomic cationic structures co-ordinated to the surface of porous matrices exhibit different properties from the same cationic species contained in a bulk oxide or supported on amorphous carriers. This subject is treated to an extensive review, showing how an understanding of it is essential to the development of a new generation of solid catalysts. There are also exciting opportunities to shape the catalytic properties of the transition metal cations in microporous and mesoporous matrices.
The book covers both theoretical and experimental aspects, including the distribution of framework Al atoms in Si-rich zeolites, distribution and siting of charge-exchanged metal cations, electronic, adsorptive and catalytic properties of metal cations, and correlation of metal cation structure and siting with catalytic activity.

Collects 19 papers presented at the July 2000 NATO workshop of the same name that address the growing awareness that advanced catalytic technologies are required for the efficient production of chemicals and the abatement of toxic emissions associated with chemical production and the combustion of fuels. The four main topics discussed are the synthesis and structural characterization of metal ion/metal oxide structure within crystalline porous materials; the effects of the interactions of metal cations with crystalline matrices and the importance of metal-ligand complexation for catalytic properties; molecular level synthesis/structure/activity/selectivity/performance relationships for redox and Lewis site catalyzed reactions; and new catalytic processes for reactions such as NO and N2O decomposition, along with selective catalytic reduction of NOx with methane or low molecular weight alkanes in the presence of oxygen selective oxidation of hydrocarbons via epoxidation of olefins and hydroxylation of aromatics.
