Abstract

Rare earth metal (Ce, La, or Pr) doped Mn-based catalysts were prepared to obtain amorphous Mn-Ce-O_x, Mn-La-O_x and Mn-Pr-O_x. Promotional effects of NO conversion at low temperature were observed after rare earth metal doping. The Mn-Ce-O_x catalyst had the best oxidation performance and the maximum NO oxidation conversion was 94.0% at the reaction temperature of 239°C. Among the reported Mn-based catalysts for NO oxidation, the Mn-Ce-O_x catalyst showed superior lowerature activity. The SEM, XRD, BET and XPS analyses further confirmed that the amorphous structure of the catalyst contributed a lot to the enhancement of activity.
