The extinction of CO oxidation occurring on the Pt catalyst in a monolithic reactor depends on the interplay of the reaction kinetics and mass and heat transfer. In particular, it may be related to a first-order kinetic phase transition from the high-reactive regime to the low-reactive regime. For this scenario, we obtain the criterion for extinction.
We present the first Monte Carlo simulations of kinetic oscillations in heterogeneous catalytic reaction with one of the key reaction steps occurring on the boundaries between the islands formed due to adsorbate-induced surface restructuring. Specifically, we treat NO reduction by CO on the Pt(100) surface with NO decomposition on the interface between the “hex” and (1× 1) phases. For this scenario,...
