Photodegradation of cobalt anime dye by using ZnO- AgCl nanocomposites

摘要

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