The transient response study of CO, CO 2 , and O 2 adsorption and CO oxidation over La 0.4 Sr 0.6 Co 0.4 Mn 0.6 O 3

The transient behaviour caused by the change of the component concentration for CO oxidation on the perovskite‐type catalyst La 0.4 Sr 0.6 Co 0.4 Mn 0.6 O 3 was investigated. Results showed that CO was not adsorbed on the catalyst surface and CO oxidation was carried out between the surface oxygen s...

Description
Summary:The transient behaviour caused by the change of the component concentration for CO oxidation on the perovskite‐type catalyst La 0.4 Sr 0.6 Co 0.4 Mn 0.6 O 3 was investigated. Results showed that CO was not adsorbed on the catalyst surface and CO oxidation was carried out between the surface oxygen species and gas phase CO. On the other hand, CO 2 can be adsorbed on the catalyst surface but its adsorption site was different from the forming site. On a étudié le comportement transitoire causé parle changement dans la concentration des composantes pour l'oxydation du CO sur un catalyseur de type perovskite La 0.4 Sr 0.6 Co 0.4 Mn 0.6 O 3 . Les résultats montrent que le CO n'est pas adsorbé á la surface du catalyseur et que l'oxydation du CO s'est produite entre les espèces d'oxygène de surface et la phase gazeuse du CO. En outre, le CO 2 peut être adsorbé sur la surface du catalyseur mais son site d'adsorption est différent du site de formation.
