Fabrication and Characterization of Cu Doped CeO₂ by Hydrothermal Process for Antimicrobial Activity

Abstract:

Cu doped CeO₂ nanopowder was synthesized by hydrothermal process at 180°C for 2~10h. The average size and distribution of the synthesized Cu doped CeO₂ nanopowder was controlled by reaction times. The crystallinity of the synthesized Cu doped CeO₂ nanoparticles was investigated by X-ray diffraction (XRD). The morphology of the synthesized Cu doped CeO₂ nanoparticles was observed by FE-SEM. The specific surface area of the synthesized Cu doped CeO₂ nanoparticles was measured by BET. The crystal size of the synthesized Cu doped CeO₂ nanoparticles decreased with decreasing reaction times. The average size of the synthesized Cu doped CeO₂ nanoparticles was below 10nm and narrow, respectively. The shape of the synthesized Cu doped CeO₂ nanoparticles was spherical type. The specific surface area of the synthesized Cu doped CeO₂ nanoparticles increased with decreasing reaction times. Antibacterial properties of Cu doped CeO₂ were analyzed by MIC method. The synthesized Cu doped CeO₂ nanopowders showed antibacterial properties against E.coli and B.sub bacteria.
