We present Monte Carlo simulations of kinetic oscillations in CO oxidation on Pt in the framework of the model including carbon deposition on and removal from the catalyst surface. Some of the elementary reaction steps (such as carbon removal and diffusion) are considered to be dependent on adsorbate–adsorbate lateral interactions. The results obtained indicate that the lateral interactions may play a key role in kinetic oscillations. In particular, the interactions may result in the appearance of oscillations and also in their suppression. The former takes place if the interactions form a feedback between the high and low reactive states of the bistable catalytic cycle. The latter may be connected, for example, with the formation of carbon islands on the surface.
