Kinetic oscillations on nm-sized catalyst particles: oxide model

We present Monte Carlo simulations of kinetic oscillations in the CO–O2 reaction occurring on nm-sized supported catalyst particles. The model used includes the conventional Langmuir–Hinshelwood mechanism of CO oxidation and oxide formation and removal. The analysis is focused on such aspects as CO supply via the support, role of this supply in synchronization of oscillations on adjacent catalyst particles, and cooperative effects in the oxide formation.
