- •
Ceria-zirconia nanomaterials are active for CO oxidation.
- •
Ceria-zirconia nano-polyhedra showed the highest activity towards CO oxidation.
- •
Worse performances have been obtained for porous catalysts with the same Ce/Zr ratio.
- •
The most active catalyst showed better redox properties and easier surface reducibility.
- •
CO oxidation over Ce-Zr mixed oxides is a structure-sensitive reaction.
