The effect of the addition of Cu on the catalytic activity of the Mn/CeO2-ZrO2 catalyst for the low-temperature SCR reaction of NO was investigated. Three different amounts of Cu, 5, 10, and 15 wt%, were impregnated on the Mn/CeO2-ZrO2 catalyst. The characteristics of the synthesized catalysts were examined by BET, XRD, XPS, and H2-TPR analyses. The de-NOx efficiency of the Cu-added catalysts increased with the amount of Cu. When 15 wt% Cu was impregnated, the deNOx efficiency was the highest, reaching as high as 99%. The increased deNOx efficiency is attributed to the enhanced reducing power stemming from the interaction between Mn and Cu on the catalyst surface.
