A molecular beam scattering investigation of the oxidation of CO on Rh(111). I. Kinetics and mechanism

Article abstract of DOI:10.1063/1.455224

The catalytic oxidation of carbon monoxide on a Rh ( 111 ) surface has been investigated using modulated molecular beam techniques.Reaction proceeds via a Langmuir-Hinshelwood mechanism.Under experimental conditions which provide a high coverage of oxygen adatoms and near zero coverage of adsorbed CO, an activation energy of 24.5 +/-0.4 kcal/mol and a preexponential factor of 2 +/-1 * 10^-3 cm² s^-1 were obtained.The angular distribution of the product CO2 is sharply peaked toward the surface normal, and cannot be described by a simple cosⁿθ expression.Present results are discussed in relation to previous work on platinum and palladium surfaces.
