Abstract

Using in situ FTIR spectroscopy and mass spectrometry, it has been demonstrated that deNOx activity in oxide-based catalysts such as ceria can be correlated to the amount of oxygen vacancies present on the surface of the material. These results have been correlated to the total amount of exchanged oxygen for ceria-based compounds.
