A lattice-gas cellular automaton model for CO oxidation on metal surfaces is developed. The model treats the dynamics of the absorbed CO and O species explicitly and incorporates the effects of surface phase transformations through simple cellular automaton rules. Nucleation and growth processes are observed and studied. Oscillations associated with surface spatial structure are also obtained when surface phase transformations are possible. The model can serve as a basis for more detailed studies of the reactive dynamics of such systems. © 1992.
