Cu۲ZnI۴/ZnO nanocomposites: In-situ synthesis, characterization and optical properties

چکیده مقاله

In this work, copper zinc tetraiodide/zinc oxide (Cu2ZnI4/ZnO) nanocomposites were successfully synthesized by simple solid-state method. The effect of various parameters such as Cu+/Zn+2 molar ratio, time and temperature of reaction on morphology, size and purity of products was investigated. The as-prepared products were characterized by X-ray diffraction (XRD), field emission scanning and transmittance electron microscopy (FESEM, TEM), and X-ray energy dispersive spectroscopy (EDS) analysis. Application of Cu2ZnI4/ZnO nanocomposite as photocatalystwas confirmed by the band gap estimated through UV–vis spectroscopy. To investigate the photocatalytic properties of this product, photooxidation of methyl orange (MO) was performed. The photocatalytic test shows that the methyl orange degradation was about 54.2% under UV irradiation for 90 min.
