Abstract

A mean-field model for study of the CO oxidation with N\(_2\)O reaction, \(\mathrm {CO\!+\!N_{2}O} \rightarrow \mathrm {N_2+CO_2}\), occurring over composite catalysts is proposed. This model involves: the bulk diffusion of both reactants and products, adsorption and desorption of molecules of both reactants, and surface diffusion of adsorbed particles based on the particle jumping mechanism via the catalyst-support interface. The model is solved numerically using a finite difference technique. The influence of the initial concentrations of both reactants, their adsorption and reaction rate constants, and particle jumping rate constants via the catalyst-support interface on the surface reactivity of the composite catalysts is studied.
