Description Alumina supported Co–K–Mo based mixed
metal oxide type catalytic materials have been prepared by
co-impregnation. These catalysts show excellent activity
for carbon as well as diesel soot oxidation, which could be
due to the redox properties of Mo and Co as well as to a
synergistic effect of molybdenum, cobalt, and K contents.
The catalyst containing 5 wt% molybdenum shows a
lowering of carbon oxidation by about 190 �C under loose
contact conditions as compared to the non-catalyzed
reaction, as well as to bare alumina. Characterization
studies suggest a composite nature of these materials, while
thermal stability investigations confirm the stable nature.
The selected catalyst has been studied by XPS, however, it
is difficult to conclude which are the important factors
contributing to the catalytic activity. It appears to be a
synergistic effect of Co, K, and Mo components as these
catalysts show much improved activity as compared to the
individual components in supported and unsupported
forms.
