Resumen : | We analyze a model recently introduced by Imbihl et al. to describe the kinetic oscillations in t~e catalytic oxid~tion of CO on Pt( 1(0). However we describe the surface reconstruction by a tIme dependent GlOzburg-Landau equation. With realistic values ofthe rate constants the region of oscillations in the P eo X Po, diagram extends to very low values of the partial pressures (Peo = 1.5 X 10-6 Torr, Po, = 2.7 X 10-5 Torr) in agreement with the experimental results. In the investigation of the critical points and of the dynamics it has been possible to identify both saddle-node infinite period (SNIPER) and Hopfbifurcations. |
