This article is the final part of a study on the CO/O 2 reaction over a 2.9% Pt/Al 2 O 3 in line with the microkinetic approach of the heterogeneous gas-solid catalysis. Mainly, the kinetic parameters of each elementary step of two kinetic models (Models M1 and M2) determined previously are used to explain the evolution of the coverage of the adsorbed CO intermediate species...
Transient experiments using mass and FTIR spectroscopy as detectors are performed at 300 K with a reduced 2.9% Pt/Al 2 O 3 catalyst to study the reduction of strongly adsorbed oxygen species (denoted O sads ) formed by O 2 chemisorption using several y% CO/z% Ar/He mixtures (y and z in the range 0.5-10). During the first seconds of the reaction C mass...
