Synthesis and Characterization of CeO₂ Powders by Thermal Assist Process

Abstract

CeO2 nanoparticles were synthesized through the solvothermal process. It is observed that the water/ethanol mixed solvents were strongly influenced on the agglomeration. The average size of CeO2 nanoparticles was about in the range of 11-13nm and its distribution was narrow. With the increase of the ethanol composition, the surface area of CeO2 was increased from 65.384m2/g to 84.649m2/g. The synthesized nanoparticles components, particle size, morphology and surface area were characterized by EDS, XRD, FE-SEM, FE-TEM and BET.
