In this work, a simple facile preparation of Ce1-xAlxO2-δ (where x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5)nanoparticles by chemical synthesis route is reported. In the preparation, appropriate quantities ofmetal nitrate salts were dissolved in water alongwith required amount of sodium hydroxide asprecipitant. The resultant precipitate mixture [Ce(OH)3 + Al(OH)3] was washed with water, filtered,dried and heat treated to get the phase pure Al doped CeO2 nanoparticles. The synthesized oxidematerials were characterized by XRD, FTIR, particle size analysis, SEM and EDAX to understandtheir structural, functional and particle properties. The XRD patterns revealed the presence of cubic(FCC) crystalline structure in the samples. The presence of Al-O and Ce-O stretching mode of vibrationwas confirmed by FTIR analysis. The particle size of the materials was found in the range of 117.23 to257.06 nm. Presence of nano and micron sized grains was noticed by SEM photographs. EDAXconfirmed the presence of appropriate atomic weight percentage of elements in the samples. The resultssuggested that the prepared Al doped ceria nanoparticles can be useful in several applications.
