Description Co3O4–CeO2 type mixed oxide catalyst compositions have been prepared by using co-precipitation method and, their catalytic activity towards
diesel particulate matter (PM)/carbon oxidation has been evaluated under both loose and tight contact conditions. These catalysts show excellent
catalytic activity for PM/carbon oxidation, despite their low surface area. The activation energy observed for non-catalyzed and catalyzed reactions
are 163 kJ/mol and 140 kJ/mol, respectively, which also confirm the catalytic activity of catalyst for carbon/soot oxidation. The promotional effects
of an optimum amount of cobalt oxide incorporation in ceria and presence of a small amount of potassium appears to be responsible for the
excellent soot oxidation activity of this mixed oxide type material. The catalytic materials show good thermal stability, while their low cost will also
add to their potential for practical applications.
