摘要：

A series of nanopowder Ce-Zr-Pr oxide catalysts were synthesized by a new method which was a low temperature synthesis approach combining rotating evaporation and auto-combustion techniques. The catalysts were characterized by means of XRD, Raman, and SEM. The results showed that the synthesized catalysts had a cubic fluorite structure, nanoparticle sizes and good catalytic activity for soot oxidation. (c) 2006 Elsevier B.V. All rights reserved.
