- •
Nanostructured cubic ceria-praseodymia catalysts were synthesized.
- •
SCS-based and nanostructured catalysts were tested for CO and soot oxidation.
- •
Catalysts containing 50% Pr showed the highest oxygen storage capacity.
- •
Nanostructured catalyst containing 50% Pr showed the highest soot combustion activity.
- •
Low-index facets (1 0 0) (1 1 0) in Ce–Pr catalysts are highly reactive for soot oxidation.
