ResumoReaction rate oscillations of the oxidation of CO were studied on highly dispersed palladium embedded within a zeolite matrix under nonisothermal conditions. Transients and periodic oscillations are interpreted in terms of an oxidation-reduction cycle involving the Pd surface which moves the system between two kinetic branches of the reaction. The observation of aperiodic oscillations can be explained by the desynchronization of the catalyst surface.
