Abstract

A new insight into the formation of NO₂ over Co/γ-Al₂O₃ catalysts during the C₃H₆-SCR of NO, which is shown not to be formed via the direct oxidation of NO with O₂, was presented. The formation of NO₂ over the 0.4 wt %/γ-Al₂O₃, in the presence of propylene, did not occur through the direct oxidation of NO by O₂. The 0.4 wt %/γ-Al₂O₃ showed yields of NO₂ even lower than that of the γ-Al₂O₃. In contrast, a high loading sample (i.e., 8 wt % Co) had a higher NO oxidation activity but showed no reduction activity and high activity for the combustion of the reductant during SCR reaction.
