采用旋转蒸发与自燃烧相结合的低温合成方法制备了一系列纳米Ce-Zr-Pr氧化物催化剂。采用XRD、拉曼光谱、SEM等手段对催化剂进行了表征。结果表明，所合成的催化剂具有立方萤石结构和纳米尺寸，对碳烟氧化具有良好的催化活性。
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.
