Abstract:
This paper reports a study on preparation of nanocrystalline ceria powder by solution combustion technique that is a simple and eco-friendly process, to take a glycine as a fuel and ammonium ceric nitrate as an oxidizer and followed by calcination at 500 ˚C for 2 h. The obtained product was characterized by various techniques and the results are presented and discussed. X-ray diffraction data confirms a cubic phase of cerium oxide with crystallite size was found to be 34.9 nm. The infrared spectrum shows the peak at ca. (413 cm-1) is corresponding to the asymmetric (O-Ce-O) stretching vibration inside CeO2 lattice.
