- Abstract
The effect of iron oxide additives on the formation of the microstructure of supported 1 wt % Pt/(Fe2O3–TiO2) catalysts, the electronic state of platinum, and the catalytic properties of the catalysts in the CO oxidation reaction has been studied. The synthesized catalyst has exhibited a higher activity than that of a 1 wt % Pt/TiO2 catalyst at identical amounts of platinum in the samples. It has been found that the introduction of iron oxide in an amount of up to 10 wt % leads to the formation of a solid solution of iron ions in titania with an anatase structure. The supporting of platinum has led to a decrease in the particle size and an increase in the content of platinum in the Ptδ+ state. An optimum chemical composition of the catalyst that provides the highest activity in the studied reaction has been determined.
