Nano cadmium hydroxide has been synthesized using PEG400 as the template at room temperature. Then this nano cadmium hydroxide recrystallizes into nano cadmium oxide at 400οC for 2 h. The products were characterized by X-ray diffraction (XRD), IR, optical absorption measurement, scanning electron microscopy (SEM) and EDAX. The effect of reaction time, temperature, solvent and molecular weight of the PEG on the formation of nanostructures CdO was investigated in detail.
