Synthesis, Structural and Morphological Properties of Cadmium Oxide Nanoparticles Prepared by Thermal Treatment Method

Abstract

Cadmium oxide (CdO) nanoparticles was synthesized from an aqueous solution containing metal nitrate as a precursor and polyvinyl pyrrolidone (PVP) as a capping agent by simple thermal-treatment method. The as-synthesized sample has been calcined at various temperatures from 500 to 650 °C to remove the organic matters. The structure and morphology of the calcined oxide nanoparticles have been examined by X-ray diffraction (XRD) and transmission electron microscopy (TEM), respectively. The results obtained supports the fact that the thermal treatment method utilized for the synthesis of CdO nanoparticles is certainly a very simple and low cost technique that requires no additional chemicals.
