In this work we applied a combined (experimental/modelling) technique, we named Kinetically Modelled Temperature Programmed Desorption (KM-TPD) using CO2 as probe molecule, to identify and quantify the active sites of copper-ceria catalysts with different Cu load prepared by wet impregnation or by solution combustion synthesis. The results of the KM-TPD showed that the model succeeded in quantitatively identifying the active sites for both CO and H2 oxidation providing a good correlation with the catalytic activity and selectivity of the catalysts.

Abstract
In this work we applied a combined (experimental/modelling) technique, we named Kinetically Modelled Temperature Programmed Desorption (KM-TPD) using CO2 as probe molecule, to identify and quantify the active sites of copper-ceria catalysts with different Cu load prepared by wet impregnation or by solution combustion synthesis. The results of the KM-TPD showed that the model succeeded in quantitatively identifying the active sites for both CO and H2 oxidation providing a good correlation with the catalytic activity and selectivity of the catalysts.File in questo prodotto:
