Synchronization of surface reactions via Turing-like structures

The radiation gas-phase coupling approach in order to explain synchronized global oscillation in CO oxidation on Pt(110) was discussed. The study was carried out by using a microscopic model which includes structural Pt surface reconstruction via front propagation and large diffusion rate for CO. It was found that the synchronization mechanism was associated with the formation of a Turing-like structure of the substrate. The results show that the use of large parallel microscopic simulations allow to extrapolate to realistic diffusion rates, pattern size and oscillation periods.
