Abstract

In this work, nanocrystalline Pd/CeO_2 catalyst had been synthesized under room temperature using microemulsion method. Cerium nitrate and palladium chloride were used as starting materials. In this procedure, two microemulsion solutions containing surfactant, co-surfactant, oil phase and aqueous solution of different reactant were prepared. One of microemulsion systems contained the mixture of Pd^<2+>and Ce^<3+> solutions that were mixed at an appropriate ratio. Another system contained sodium hydroxide solution. Both solutions were then mixed at room temperature producing the Pd/CeO_2 nanoparticles. Structure and properties of the synthesized particles were investigated using XRD, TEM, and gas adsorption-desorption analysis. It was found that the crystal structure of synthesized particles was FCC with an average crystallite size of about 4 nm. The average size of particles investigated using TEM was found to be around 4.1 nm.
