Homogeneous and Heterogeneous Catalysis Proceedings of the Fifth International Symposium on Relations Between Homogeneous and Heterogeneous Catalysis, USSR

This Proceedings contains plenary lectures and selected poster communications spanning the entire field of catalysis --- from catalysis by protons to catalysis by multinuclear clusters and ultra-disperse particles. It includes discussion of the recent results of fundamental research conducted at the juncture between homogeneous and heterogeneous catalysis. New ideas, based on modern physical and quantum-chemical methods, and concerning the mechanism of formation and functioning of active sites of catalysts are suggested. It is shown how the cyclic change of atomic distribution in the active site occurs during catalytic transformations. In addition, the Proceedings report new data on methods of ''assembling'' molecularly organized catalytic systems and on the mechanisms of their action. The various problems such as the effect of strong metal--support interaction, migration of atoms in active sites, and design of catalytic properties of substances are also widely discussed. Similarities and differences in mechanisms of action of homogeneous and heterogeneous catalysts are considered, using as examples CO hydrogenation, hydrogenolysis of saturated hydrocarbons, selective hydrogenation and oxidation of olefins, metathesis and polymerization of olefins, hydrosilylation and hydroformylation of olefins, etc.
