The nanocomposites were prepared by a novel and facile ultrasonic-assisted hydrothermal method, and their effectiveness was evaluated for photocatalytic degradation. X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and N2 adsorption–desorption methods were performed to characterize the prepared catalysts. The photocatalytic activity of Fe3O4–TiO2–Ag was studied by illumination of 4-chlorophenol (4-CP) in an aqueous solution under UV irradiation, which showed significant enhancement in the degradation of 4-CP compared to un-doped nano TiO2. The maximum degradation of 97% in 165 min for Fe3+ and Ag+ with 0.3 and 2% wt. was observed. Furthermore, the stability and reusability of the synthesized catalysts were studied and demonstrated only 3% decrease in removal efficiency after five cycles.}, number={2}, journal={International Journal of Industrial Chemistry}, publisher={OICC Press}, author={Shojaie, Amir and Fattahi, Moslem and Jorfi, Sahand and Ghasemi, Bahram}, year={2023}, month={Nov.}, keywords={4-Chlorophenol, Ag doped TiO2, Hydrothermal synthesis, Photocatalytic Degradation, UV irradiation} }
