Title:Influence of global coupling through the gas phase on the dynamics of CO oxidation on Pt(110)
Creators Name:Falcke, M. and Engel, H.
Abstract:In CO oxidation on platinum single-crystal surfaces spatial coupling takes place via two basic mechanisms: locally by surface diffusion of mobile adsorbates and globally by pressure changes in the gas phase. The effect of these two competing coupling modes on the dynamics of the reaction is studied using a reaction-diffusion model supplemented by an equation for the balance of the partial pressure of CO in the gas phase. The integral reaction rate and the associated spatiotemporal patterns of CO coverage show strong influence of coupling through the gas phase.
