The synthesis of nanosize single phase CeO2 by gelatine gel combustion method was investigated. The prepared material was characterized by X- ray diffraction, thermogravimetric and differential thermal analysis, scanning electron microscopy and transmission electron microscopy measurements. At optimum conditions, such as pH 3, the molar ratio of Ce4+ /gelatine 1/1, and a calcination temperature of 550 oC for 2 hours, the material with average size < 30 nm was synthesized.
