| Research Abstract |
Novel functional ceria (CeO_2) nanoparitices with different morphology in hydrothermal solution including carbonate ion have been developed. Cerium carbonate with nanowires, nanorods, nanosheets morphology has been successfully synthesized using surfactants. Their morphologies were sustained after thermal decomposition-oxidation to ceria. Each ceria nanoparticles synthesized using surfactant exhibited higher oxygen storage capacity than ceria nanoparticles synthesized without surfactants. These ceria nanoparticles showed superior activity for the carbon combustion than JRC-CEO-1.
