Spiral concentration waves in the Monte Carlo model of CO oxidation over Pd(110) caused by synchronisation via COads diffusion between separate parts of catalytic surface
The role of adsorbed CO diffusion as a synchronisation factor between the separate oscillating surfaces in CO oxidation reaction has been examined by means of Monte Carlo model. As a result of the chosen simulation strategy the spiral waves of adsorbed species on the palladium surface (imagined as a set of independent Pd(110) planes) have been observed. The dependence of the results on the details of the simulation experiment as well as on the size of the lattice representing the catalytic Surface has been studied.
