Ag[1-butyl 3-methyl imidazolium]Br nanospheres were prepared by a coprecipitation method at ambient temperature. The obtained products were characterized by X-ray diffraction (XRD) (Fig. 1), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Diffusion Reflectance Spectra (DRS), the Brunauer−Emmett−Teller (BET) nitrogen adsorption-desorption isotherms, and Fourier Transform Infrared spectroscopy (FTIR) analysis methods. Their photocatalytic properties were evaluated by degradation of Acid Blue 92 (AB92) and rhodamine B (RB) dye solutions under visible irradiation and the results compared with the earlier works [1, 2]. According to the recycling experiments, the samples were able to minimize the concentration of the pollutant after four times of repeated using. To assure the practical capacity, photodegradation of a real wastewater related to the textile industry was studied under same conditions and the results indicated that the concentration of the wastewater decreased efficiently after photocatalytic treatment.
