Title
Simultaneous removal of soot and NO over thermal stable Cu–Ce–Al mixed oxides
Abstract

Cu–Ce–Al mixed oxides were synthesized by depositing Al2O3 powders in Cu–Ce gel and then were treated at 800 °C in air for 10 h. The modification of Al2O3 obviously increases the textural stability of the catalyst and improves the dispersion of CuO and CeO2, which induces a lower soot oxidation temperature and a higher simultaneous NO reduction. In addition, the adsorption behavior of NOx on the Cu–Ce–Al surface is quite different from that for Cu–Ce, which may be also an important factor for the improved activity.
