Abstract:
Use of physical methods with a high space resolution (<1 μm) made it possible to study in situ the formation of traveling chemical waves arising from the oscillatory dynamics of the reaction on Pt and Pd single-crystal surfaces. It was demonstrated that the conventional approaches using phenomenological kinetic equations (sets of differential equations) are inappropriate for describing the nature of spatiotemporal chemical waves on the metal surface. So-called kinetic (dynamic) Monte Carlo models turned out to be the most suitable. Here, we present an overview of our Monte Carlo studies of the formation of self-oscillations and chemical waves in CO oxidation reaction over Pt(100) and Pd(110) single crystals, based on experimental data. The kinetic models for these surfaces differ in the detailed mechanism of the appearance of oscillations. Both models indicate oscillations of the CO2 formation rate and adsorbed species concentrations. The oscillations are accompanied by wave phenomena on the model surface.
