Abstract
We present a first step towards the modeling of adsorption and desorption of CO in empty sites during its catalytic oxidation on a Pt monocrystalline surface (2 CO + O2 → 2 CO2). After a diffusion process on the Pt surface, the CO and O reacts at the moment of their encounter in the same site. The cristalline structure of the surface suffers a phase transition that governs the dynamics of the problem, turning from a cubic 2-D lattice, when occupied by CO to an hexagonal one after desorption.
