Comment on `Modelling pattern formation in CO + O2 (reaction) on Pt{1 0 0}ʹ

I.M. Irurzun, R.B. Hoyle, M.R.E. Proctor and D.A. King [Chem. Phys. Lett. 377 (2003) 269] have recently proposed a novel coarse-grained approach to describing the transport of adsorbed CO molecules along the quasi-hexagonal and (1 × 1) patches during kinetic oscillations in CO oxidation on the Pt(1 0 0) surface. Our analysis indicates that this approach cannot be used as a robust tool for analysing the pattern formation in oscillatory catalytic reactions, because it contradicts the basic principles of general theory of mass transport.
