Abstract :
Nanomaterials have achieved remarkable technological advances in bulk materials
due to their excellent physical, chemical and biological properties. cerium oxide (CeO2)
nanostructured doped with Fe ions is attractive due to improvement in redox properties,
transport property and surface-to-volume ratio. In this research, Fe-doped CeO2
nanoparticles (NPs) were prepared by simple solgel method. The as-synthesized and
annealed samples were studied by transmission electron microscopy (TEM), field
emission scanning electron microscopy (FESEM) and x-ray diffraction (XRD). The
XRD result revealed the cubic crystal structure of Fe-doped CeO2 NPs. The FESEM
images showed that the uniformity of the NPs increase with increasing calcination
temperature. The TEM studies demonstrated the 20 nm uniform NPs.
