    “…High N(2) selectivity at elevated temperatures is due to N(2)O decomposition on oxygen vacancies. Doping CeO(2) by Fe is predicted to lead to more oxygen vacancies and a higher N(2) selectivity, which is validated by the lower onset of N(2) formation for a Pd catalyst supported on Fe-doped CeO(2) prepared by flame spray pyrolysis. …”
