Cu-Supported on Acid-Treated Sepiolite: Characterization and Selective Catalytic Reduction (SCR) of NO by Propene

Abstract:

H-Sep samples were taken from treating sepiolite with HCl solution. Cu/H-Sep samples were prepared by the incipient wetness impregnation method. The samples were characterized using XRF, XRD, and XPS techniques, and their catalytic activities were performed by the SCR of NO with propylene. The results show that the Cu/H-Sep catalyst exhibited the high performance in the C₃H₆-SCR of NO. After investigation by XRD and H₂-TPR, the result showed that there are Cu²⁺/Cu⁺ redox species as a reaction activity center over Cu/H-Sep.
