| Abstract: | The article presents a detailed bifurcation analysis of steady and periodic states for a new mathematical model of the NO+CO/Pt(100)
reaction. Various bifurcation diagrams are constructed in the planes of partial reagent pressures and surface temperature.
Regions with oscillations and multiple steady solutions are investigated. Isolated branches of steady and periodic states
are identified. An “explosive” bifurcation of the periodic solution leading to chaotic alternation of small-and large-amplitude
oscillations is detected and analyzed for the first time. A good quantitative fit is demonstrated between modeling results
and experimental data.
