Influence of CeO₂ additives on the physical-chemical and catalytic properties of Ag/Fe₂O₃ catalysts for deep oxidation of toluene

The influence of CeO₂ additives on the physicochemical and catalytic properties of Ag/Fe₂O₃ catalysts for deep toluene oxidation is considered. It is established that the introduction of CeO₂ additive into the carrier composition promotes an increase in the dispersion of oxides, as well as the reactivity of the 1Ce6Fe sample surface. A synergistic effect of catalytic action in the reaction of deep toluene oxidation for the Ag/1Ce6Fe sample is established, consisting in an increase in reactivity due to the interaction of dispersed CeO₂ and Fe₂O₃ oxides and deposited silver.
