Surface Structure and Catalytic CO Oxidation Oscillations
A cellular automaton model is used to describe the dynamics of the catalytic oxidation of CO on a Pt(100) surface. The cellular automaton rules account for the structural phase transformations of the Pt substrate, the reaction kinetics of the adsorbed phase and diffusion of adsorbed species. The model is used to explore the spatial structure that underlies the global oscillations observed in so...
متن کاملReaction Rate Oscillations during Catalytic Co Oxidation- a Brief Overview
INTRODUCTION It is not our intent here to present a comprehensive review of the dynamic behavior of the catalytic oxidation of CO. This reaction is one of the most widely studied in the field of catalysis. A review paper by Engel and Ertl [ l ] has examined the basic kinetic and mechanistic aspects, and a comprehensive paper by Razon and Schmitz [2 ’J was recently devoted to its dynamic behavio...
متن کاملSynthesis, Structure and Catalytic Performance of N4-Macrocycles of Fe III and Co II for Oxidation of Hydroquinone
Macrocycles and p-benzoquinones (p-BQ) have been generally connected as potential co-synergist redox models in aerobic oxidation. To get insight for the synergist oxidation of hydroquinones (H2Q), thus, we synthesized and characterized dibenzotetraaza [14]annulene type macrocycles of FeIII and CoII metal ions and described by utilizing different examinations inc...
متن کاملCatalytic CO oxidation by free Au2-: experiment and theory.
Temperature-dependent rf-ion trap mass spectrometry and first-principles simulations reveal the detailed reaction mechanism of the catalytic gas-phase oxidation of CO by free Au(2)(-) ions in the presence of O(2). A metastable intermediate with a mass of Au(2)CO(3)(-) was observed at low temperatures. Two alternative structures corresponding to digold carbonate or peroxyformate are predicted fo...
متن کاملCO oxidation on ruthenium: The nature of the active catalytic surface
The oxidation of CO, i.e. CO + =2O2 ! CO2, over metal surfaces is one of the most studied catalytic reactions. The details of the reaction mechanism under ultrahigh vacuum (UHV) conditions have been well understood for some time [1]. Under reducing or mildly oxidizing conditions for Pt, Pd, and Rh, metals used in automotive catalytic converters, the reaction proceeds via the Langmuir–Hinshelwoo...
