We present the results of the modelling of catalytic CO oxidation with taking into account the diffusion processes of the carbon monoxide molecules over the inhomogeneous Pt(110) surfaces which contain structurally different areas. These areas are formed during the CO-induced transition from a reconstructed phase with 1⨯2 geometry of the overlayer to a bulk-like (1⨯1) phase with square atomic arrangement. On the inhomogeneous surface, we find spatio-temporal surface structures of the oxygen coverage, as well as the fraction of the surface of the 1⨯1 structure.
