Abstract
It is a common drawback and the reason for many contradictions among the different theories of catalysis (acid-base-, electronic-, multiplet-, ligand field-, etc.) that each concept about the mechanism of the catalytic reaction is throughout onesided. Here we will try to formulate the determining characteristics of the mechanisms (DCM) of catalytic reactions, which could now be regarded as a good approximation of the essential features of the mechanisms. The concrete meaning of the six DCM's defined here is illustrated by possible mechanisms of catalytic double bond isomerization of olefins and of the oxidation of CO. We have shown that the subsequent systematic application of the DCM allows to systematization of the possible mechanisms of catalytic reactions, the evaluation of the real potential of each experimental method for the determination of the mechanisms (the CO oxidation on Cr 2O 3-MoO 3 as a concrete example) and the critical evaluation of the individual theories of catalysis.
