Preparation, characterisation and testing of CuO/Ce0.8Zr0.2O2 catalysts for NO oxidation to NO2 and mild temperature diesel soot combustion

- Very low copper content increases ceria-zirconia's activity for NO oxidation.
- 2% CuO/Ce0.8Zr0.2O2 is the optimum formulation found for mild soot combustion.
- Copper/ceria-zirconia can be competitive versus platinum for DPFs regeneration.
