Synthesis and Characterization of CdO Nanomaterial and their Photocatalytic Activity

Abstract

Nano-sized cadmium oxide was synthesized by a simple hydrothermal method using CdCl2.H2O as a metal precursor in the presence of polyethylene glycol and urea.The synthesized nanoparticles were characterized by X-Ray diffraction (XRD), transmission electron microscopy (TEM), UV-visible spectroscopy and FT-IR.Also adsorption of methyl red dye was carried out using CdO nanoparticles. The XRD analysis of the nanoparticle showed the crystalline phase with particle size 65nm. UV-Visible spectra and FTIR shows the formation of CdO bond. The TEM studies show the formation of spherical ring structure of the CdO nanomaterial.The photocatalytic activities of CdO nanoparticles were evaluated by measuring the degradation of Methyl red (MR) in water under the UV region. The degradation percentage were found to decrease with increase in concentration of the organic pollutant.
