Synthesis and Characterization of Nano Cerium Oxide by Surfactant-Assisted Precipitation Method

Abstract:

Cerium oxide is an important material having been applied to a variety of commercial fields. Many methods such as precipitation, hydrothermal route and sol-gel techniques have been used to produce the nanocrystalline ceria. This study, based on the precipitation method, used ceric nitrate as cerium source, anionic surfactant (sodium dodecyl sulphate) as template, and urea as the precipitating agent to synthesize ceria. The effects of several factors, such as the molar ratio of reactants and reaction temperature on the morphology and crystal structure of ceria were investigated, which were determined by XRD and SEM methods. According to the results, 70°C is best experimental conditions and preferable molar ratio of chemicals mentioned above is 1:2:30 for single factor experiment.
