Spatiotemporal patterns in CO oxidation on Pt(110): the role of nonlinear diffusion.
Standing-wave patterns observed in the CO + O2 reaction on Pt(110) are described by a model that explicitly takes into account the coupling between the transport of adsorbed CO and the adsorbate-induced structural transformation of the substrate. We show that synchronization of the surface is achieved through nucleation and growth processes even in the absence of gas-phase coupling.
