Abstract
Abstract4-Chlorophenol (4-CP), widely used in the production of dyes, drugs, and fungicides is a water pollutant. It can be found in surface water, soil, ecosystems, and the human body. 4-CP is a non-degradable pollutant when subjected to traditional water treatment techniques. The development of advanced oxidation processes provided alternative methods that could potentially be applied to the decomposition of non-degradable compounds; 4-CP could then be removed from water supplies by processes such as photocatalytic degradation. However, the anatase TiO2 typically used in such procedures has a large band gap of 3.2 eV which is only activated by ultraviolet (UV) radiation. In this study, a Ag/TiO2/Fe3O4 composite was synthesized from Ag, TiO2, and Fe3O4 owing to the enhanced photocatalytic activity and catalyst recoverability conferred by Ag and Fe3O4, respectively. The catalyst was characterized by X-ray diffraction, X-ray fluorescence, UV–visible spectrophotometry, scanning electron microscopy, transmis...
