A simple solid-state approach for synthesis and characterization of CdO-ZrO_2-CdZrO_3 nanocomposites

摘要

CdO-CdZrO_3-ZrO_2 nanocomposites, with the aid of Cd(C_2O_4)·3H_2O and Zr(C_2O_4)·4H_2O 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-CdZrO_3-ZrO_2 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-CdZrO_3-ZrO_2 nanostructure was evaluated by degradation of methyl orange in aqueous solution under UV-light irradiation.
