Photodegradation of cobalt anime dye by using ZnO- AgCl nanocomposites

Abstract

AgCl–ZnO nanocomposites were successfully prepared by usingsimple one-pot refluxing method.TheseNanocomposites were preparedand characterized by using X-ray diffraction (XRD), Scanning electron microscopy (SEM) and UV-Visible spectroscopy.Photocatalyticactivityof nanocomposites were evaluated in the degradation of cobalt amine dye (used as model pollutant) in aqueous solution under solar light and atmospheric oxygen. The decolorization efficiency of cobalt amine on the surface of nanocomposite and solar light in presence of atmospheric oxygen is about 93.2%.Influence of various operational parameters on the degradation reaction was studied and the results were discussed. The mechanism of ZnO-AgClnanocompositeillumination to produce oxidizing species and the effect of these species on the photodegradation activity in aqueous solution was suggested.
