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

Why is it important?

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.
