Improving ceria-zirconia soot combustion catalysts by neodymium doping

- Nd-doping improves the soot combustion activity in NOx/O2 of Ce-Zr oxide catalysts.
- Nd-doping of Ce-Zr catalysts improves NO oxidation to NO2.
- Nd-doping of Ce-Zr catalysts favors the formation of less stable ad-NOx species.
