STATISTICAL MODELLING OF ADSORPTION PROCESSES ON CATALYST SURFACES:PRELIMINARY REPORT

摘要

A three-faceted approach has been fruitful in modelling surface reactions involved in heterogeneous catalysis. The chemisorption re-actions have been modelled as immobile binding, involving adjacent sites on the solid surfaces, forming the "activated intermediate" which is the key step in most intrafacial or suprafacial catalytic processes. The kinetics and stoichiometry of these processes have been analyzed by a detailed comparison of experimental data, computer simulation, and mathematical analyses. Several unexplained experimental results are satisfactorily interpreted in terms of these models on a semi-quantita-tive basis. Previously, qualitative explanations had been proposed which embodied much of the logic of our models. The results are adequately developed to determine, by inference, the lattice structure of the surfaces in terms of the kinetics and stoichiometry of the adsorption processes. The results of this preliminary study are en¬couraging and lead us to conclude that additional analyses will be beneficial in interpreting surface reactions of interest in the field of heterogeneous catalysis.
