The prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Brunauer-Emmett-Teller (BET). All three compounds were confirmed to be pure with the associated planes being identified. The photocatalytic activity of these photocatalysts were evaluated through the degradation of 2,4-dichlorophenol (2,4-2,4-DCP) under UV and visible light irradiation. Variant photocatalytic efficiency was exhibited dependent on the material used. The Ag/AgBr photocatalysts exhibited the best efficiency among all three catalysts, resulting in an 83.37 % and 89.39 % photodegradation under UV and visible light after 5 h, respectively, at a catalyst loading of 0.5 g/L.en© 2021, AIDIC Servizi S.r.l.Photocatalytic degradationSilver halide (Ag/AgX where X= Cl, Br, I)PhotocatalystsVisible lightActivationX-ray diffraction (XRD)Scanning electron microscopy (SEM)Brunauer-Emmett-Teller (BET)Article
