A simple solid-state approach for synthesis and characterization of CdO-ZrO۲-CdZrO۳ nanocomposites

چکیده مقاله

Abstract CdO–CdZrO3–ZrO2 nanocomposites, with the aid of Cd(C2O4)3H2O and Zr(C2O4)4H2O as starting reagents, have been successfully synthesized by a simple solid-state process from ethanol solution. Besides, the effects of preparation parameters such as calcination temperature and molar ratio of Zr:Cd on the morphology and particle size of products were studied. The prepared CdO– CdZrO3–ZrO2 nanostructures were characterized extensively by means of X-ray diffraction, energy-dispersive X-ray analysis, scanning electron microscopy, transmission electron microscopy, infrared spectrum and UV–Vis diffuse absorption spectroscopy. The photocatalytic activity of CdO–CdZrO3–ZrO2 nanostructure was evaluated by degradation of methyl orange in aqueous solution under UV-light irradiation.
