Redox properties and VOC oxidation activity of Cu catalysts supported on Ce1−xSmxOδ mixed oxides

- Complete elimination of ethyl acetate is achieved at 260 °C with Cu/CeO2 catalysts.
- Samarium has a detrimental impact on VOC oxidation, proportional to its content.
- Incorporation of Sm in ceria has a detrimental effect on textural characteristics and reducibility.
- Increase of Sm/Ce ratio results in a more reduced Cu species, inactive for VOC oxidation.
- A correlation between VOC activity and catalysts redox properties is established.
