Ceria nanoparticles were prepared using a solution based approach using cerium (III) acetate as a starting material and cetyltrimethylammonium hydroxide (CTAOH) as a precipitating agent and surfactant. The presence of the surfactant CTAOH helps prevent agglomeration of the nanoparticles. Using X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM), the particle size was determined to be 3.5 – 4 nm. The structure and properties of these CeO2 nanoparticles have been analyzed.
