ABSTRACT

Ceria (CeO2) is a rare earth oxide, which has been widely investigated to improve the property. It is important to increase the surface area of CeO2, because high surface area of CeO2 can improve the catalytic ability. CeO2 nanoparticles were synthesized by a solvothermal process. A discussion on the influence of solvent ratio and precursors on CeO2 nanoparticles was performed. The size and degree of the agglomeration of the synthesized CeO2 could be tuned by controlling those parameters. The average size and distribution of prepared CeO2 powders was in the range of 3 to 13 nm and narrow, respectively. The XRD pattern showed that the synthesized CeO2 powders were crystalline with cubic phase of CeO2. The average particle size was calculated by Scherrer equation and FE-TEM images. The morphology of the synthesized CeO2 particle was objected using FE-TEM and FE-SEM. Specific surface area of the synthesized CeO2 was determined using BET (Brunauer-Emmett-Teller) equation.
