Abstract

Fe/CeO2 nanoparticles (NPs) were synthesized by simple co-precipitation method Iron chloride hexahydrate (FeCl3.6H2O) and cerium chloride (CeCl2·5H2O) as precursor in the presence of polyvinylpyrrolidone (PVP) surfactant and ethylene glycol agent. The samples were characterized by high resolution transmission electron microscopy (HRTEM), field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and electron dispersive spectroscopy (EDS) in different temperature. The XRD results showed that Fe-doped CeO2 was single-phased with a cubic structure. The particle size of as-prepared sample was in the range size of 15-45 nm and annealed sample was around 22 nm in diameter at 800oC for 3 hours. The TEM studies showed the 17 nm squared-like shaped nanosized particles. EDS shows peaks of iron and cerium with less impurity in prepared samples and Fe/Ce ratio was also decreased with increasing annealing temperature.
