Abstract

In this study, Ag/AgCl/TiO2 nanocomposites were synthesized by deposition–precipitation along photoreduction method and their photocatalytic performance was tested for removal of congo red under visible-light irradiation. Design of experiment with Taguchi method was employed to optimize synthesis parameters of composite such as the loading percentage of silver, the type of chlorine precursor, the duration of UV light radiation, the calcination temperature and the ratio of chloride to silver and also process parameters including photocatalyst dosage and dye concentration. According to results, dye concentration and type of chlorine precursor are significant factors. The optimal level of factors was precursor HCl, Cl/Ag ratio 2, silver loading 70%, 30 min exposure to UV light radiation, without calcination and photocatalyst dosage 700 ppm. The under optimum condition, high concentrations of congo red can be removed with high efficiency (96, 91 and 86% removal at concentration 30, 50 and 70 ppm, respectively). The synthesized nanocomposites were characterized by X-ray diffraction, scanning electron microscopy and UV–vis diffuse reflectance spectra.
