Abstract
In the paper a study of a two-dimensional mathematical model of carbon monoxide oxidation on the Pt catalyst surface according to the Langmuir-Hinshelwood mechanism is presented. This model takes into account the nanoinhomogeneities of Pt(110) surface and diffusion processes of CO molecules and oxygen atoms adsorbed on the catalyst surface. It is shown that the structural changes of Pt(110) surface significantly affect the character of oscillatory mode of reaction, whereas the adsorbed oxygen atoms can be considered immobile.
