Non-Thermal Effects on CO–NO Surface Catalytic Reaction on Square Surface: Monte Carlo Study

Abstract

A Monte Carlo simulation of the CO–NO heterogeneous catalytic reaction over a square surface has already been studied with a model based on the Langmuir–Hinshelwood (LH) mechanism. The results of this study are well known. Here we study the effects of transient non-thermal mobility of monomer (CO) based on precursor mechanism, diffusion of adsorbed nitrogen and oxygen atoms, on the phase diagram. The interesting feature of this model is the yield of a steady reactive window, while simple LH mechanism is not capable of producing a steady reactive state.
