Evolution of heterogeneous catalytic reactions kinetics with time

An overview of development of heterogeneous catalytic kinetic concepts is presented. An emphasis is made on the application of mechanistically sound models, which are needed as a part of the understanding of catalytic reactions on a molecular level as well as of the design and the intensification of chemical processes. Such models should include among other parameters the size and geometry of reacting molecules, size of nanoclusters and deactivation as a part of the reaction mechanism.
