The zinc oxide and zinc-cerium (ZC) oxide composites have been synthesized by varying zinc (Zn) and cerium (Ce) ratios to obtain different Zn1 – xCexO2 compounds using the hydrothermal method. The composition of the samples was varied with x = 0.0, 0.05, 0.1, 0.3 and 0.5 to obtain compounds named as ZC-1, ZC-2, ZC-3, ZC-4 and ZC-5, respectively. To understand the effect of cerium on zinc oxide, all samples were characterized by FT-IR, SEM-EDX and TGA-DSC. The effective doping of cerium with zinc is confirmed by FT-IR and EDX. All samples were obtained with different particle sizes. Initially, ZC-1 had rod-shaped particles and by doping cerium the particles slowly turned to quasi-spherical shape with reduced size from 150 nm to 60 nm. From thermal studies, the cerium doped zinc oxide showed higher stability than the undoped zinc oxide. The detailed analysis of the properties indicates that these composites can be potential candidates for the biological applications and also they can be promising for catalysis and dye degradation.
