Abstract: It has been observed that the catalytic CO oxidation on a (001) surface and subsurface of a body centred cubic structure (which extends to only two layers in the z-direction) exhibits temporal kinetic oscillations under certain conditions. In order to describe such oscillations a mechanism is presented in which at high oxygen partial pressure slow formation/removal of subsurface oxygen modulates the catalytic activity of the surface. The simulated results agree with experimental observations qualitatively.
