Outline of Final Research Achievements

We have shown that facet-controlled CeO2 nanoparticles had high oxygen storage capacity. In this study, we studied the doping of metal atoms in CeO2 nanoparticles to improve oxygen storage capacity. By synthesizing CeO2 nanoparticles with Cr ion in reactant solution, we have synthesized Cr-doped CeO2 nanoparticles. The Cr-doped CeO2 nanoparticles showed higher oxygen storage capacity.
