Abstract:
Nano-sized cerium oxide (CeO2) was synthesized successfully by a simple method using polyethylene glycol (PEG 2000) as a nonionic surfactant and different precipitating agents.X-ray diffraction (XRD) scanning electron microscope (SEM) and transmission electron microscope (TEM were used to characterize the structure and morphology synthesized powder. The nanocrystaline CeO2 was grown in face-centered cubic. Sample prepared by triethylamine as precipitating agent possess spherical nano-sized particle with the average crystallite size 25 nm.
