Catalyst-substrate interaction and the effects of self-central and self-organization in catalysis

The mechanisms and kinetics of catalytic reactions in the systems where a c atalytic reaction is coupled with the transformations of a catalyst (active sites) are theoretically analyzed. The mechanism of active site "protectio n" existing in these systems provides positive feedback, which is responsib le for their self-control features. A subsystem (catalyst) may settle itsel f farther from equilibrium in the course of a catalytic reaction by way of spontaneous sophistication, which may be a factor of evolution. Kinetic fea tures of a catalytic reaction in a self-controlled system and the condition for the appearance of the above effects are discussed using the reactions of Fischer-Tropsch synthesis, CO oxidation, and alcohol sulfoesterification , as examples.
