A novel preparation method was developed for the preparation of iron and gold/iron supported catalysts using metallic carbonyl clusters as precursors of highly dispersed nanoparticles over TiO2 and CeO2. A series of catalysts with different metal loadings were prepared and tested in the complete oxidation of methanol and the preferential oxidation of CO in the presence of H2 (PROX) as model reactions. The characterization by BET, XRD, TEM, H2-TPR, ICP-AES and XPS spotlights the interaction between Au and Fe and their influence on the catalytic activity.

Abstract

A novel preparation method was developed for the preparation of iron and gold/iron supported catalysts using metallic carbonyl clusters as precursors of highly dispersed nanoparticles over TiO2 and CeO2. A series of catalysts with different metal loadings were prepared and tested in the complete oxidation of methanol and the preferential oxidation of CO in the presence of H2 (PROX) as model reactions. The characterization by BET, XRD, TEM, H2-TPR, ICP-AES and XPS spotlights the interaction between Au and Fe and their influence on the catalytic activity.
