Synthesis of nanopowder Ce-Zr-Pr oxide solid solutions and their catalytic performances for soot combustion

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.
