However, their thermal stability has been a limitation. Ruthenia-based catalysts have been prepared by supporting different amounts on titania by the impregnation method. These ruthenia-based catalysts show good catalytic activity for carbon/soot oxidation, which could be due to the improved surface area of titania-supported materials as well as the synergistic effect. Catalysts also show improved thermal stability, which is probably due to the formation of solid solution. Dissociative adsorption of oxygen on Ru sites appears to be the plausible mechanism for catalytic activity. It appears possible to influence the catalytic properties of RuO2 through solid solution formation with similar oxides. Such materials show potential for their possible applications in the regeneration of diesel particulate filters.
