Catalytic oxidation of propylene, toluene, carbon monoxide, and carbon black over Au/CeO₂ solids: comparing the impregnation and the deposition-precipitation methods.

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.
