Temporal dynamics of a heterogeneous catalytic system, namely of the
catalytic CO oxidation on Pt(110) surface at low pressures, is
investigated with taking into account the adsorbate-driven
structural transformations of the catalyst surface. Uniform temporal
periodic chemical oscillations of the CO and oxygen coverages, and
the fraction of the surface of the 1x1 structure are
obtained in a narrow region of phase diagram between two uniform
stable states of high and low catalytic activities, respectively.
Key words:
chemical oscillations, bifurcation, catalytic oxidation, carbon monoxide, oxygen
