Catalytic Oxidation of Propylene, Toluene, Carbon Monoxide, and Carbon Black over AuCeO2 Solids: Comparing the Impregnation and the Deposition-Precipitation Methods

الملخص EN

Au/CeO2 solids were prepared by two methods: deposition-precipitation (DP) and impregnation (Imp).

The prepared solids were calcined under air at 400°C.

Both types of catalysts have been tested in the total oxidation of propylene, toluene, carbon monoxide, and carbon black.

Au/CeO2-DP solids were the most reactive owing to the high number of gold nanoparticles and Au+ species and the low concentration of Cl- ions present on its surface compared to those observed in Au/CeO2-Imp solids.
