Surface reactions on single crystal substrates have received a great deal of recent interest. These reactions are far-from-equilibrium, and can be modeled using a variety of contemporary techniques in statistical physics. Various models for CO-oxidation and a model for NO reduction by CO are studied using mean-field rate equations, reaction-diffusion equations, and Monte-Carlo simulations. Techniques are developed and applied to study the phase diagram and critical phenomena in the CO-oxidation models. Detailed theories of transport in disordered systems are developed and applied to describe chemical wave propagation in both the CO-oxidation models and the NO-reduction model.
