Description Various amounts of ruthenia–cobaltate bimetallic catalyst supported on zirconia have been prepared by co-impregnation
method and their catalytic activity towards soot/carbon oxidation has been evaluated using TG technique under the loose contact
condition. These catalysts show good activity for carbon/soot oxidation, which is observed to be a factor of ruthenia content. The
thermal stability experiments confirmed the stability of catalytic materials in air at least up to 900 �C. In this way, ruthenia can be
easily dispersed on zirconia possibly through the solid solution formation, while its thermal stability can be significantly improved
by introducing a transition metal namely cobalt. Formation of Ru–Co bimetallic clusters over zirconia is probably responsible for
its thermal stability, while dissociative adsorption of oxygen on catalyst surface appears to be responsible for their catalytic activity.
