A two-dimensional mathematical model for carbon monoxide (CO) oxidation on the platinum (Pt) catalyst surface is investigated according to the Langmuir-Hinshelwood (LH) mechanism.   The effects of structural changes of the catalytic surface, the substrate temperature and desorption of the product of reaction (CO2) are taken into account.  It is shown that taking into account the finiteness of CO2 desorption, both the course of oxidation reaction and the stability region are only slightly affected.
