Fabrication and Characterization of Ag Doped CeO2 Nanoparticles By a Hydrothermal Process

Ag doped nanocomposite catalysts, such as Ag@CeO 2 , were investigated to evaluate the influence of metal doped morphology on catalytic performance in the antibacteria. The Ag doped CeO 2 nanocomposite catalysts were synthesized by hydrothermal process. The catalysts were characterized by use of XRD, antibacteria test, TEM, and TGA. The Ag@CeO 2 catalysts with a doped ceria nanostructure exhibited superior catalytic activity over the catalysts prepared by impregnation of Ag on a CeO 2 support in solution. The high catalytic activity on a nocomposite catalysts in solution is mainly attributed to the improved surface area by doped ceria catalyst morphology.
