Abstract:CeO 2 nanoparticles with good monodispersity and narrow size distribution were synthesized by the coupling route of W/O microemulsion with homogenous precipitation. The morphology, size, size distrbution and the crystal structure of CeO 2 nanoparticles were inspected. It was found that the sort of surfactants and the relative initial concentration of reactants have regular affections on the average size of products. The average size of products increases sharply with the calcination temperature. Research results may present a promising method for the synthesis of nanoparticles with controlled size and size distribution.
Keywords:Microemulsion  Homogenous precipitation  Nanometer  Cerium dioxide
