Cu-Supported on Sodium-Treated Sepiolite for Selective Catalytic Reduction of NO by Propylene

Abstract:

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