A two-dimensional mathematical model for carbon monoxide oxidation on the platinum catalyst surface is investigated according to the Langmuir--Hinshelwood mechanism.  This model takes into account the influence of diffusion effects on the course of reaction-diffusion processes.  It is established that the diffusion of adsorbed oxygen atoms can be neglected, and the structural changes of the catalyst surface have a significant influence on the character of oscillatory mode of reaction.
