Synthesis and characterization of Fe-TiO2 composite as a photocatalyst in the photodegradation of methylene blue on visible light irradiation in a closed reactor have been carried out. Synthesis was conducted by the sol-gel method at room temperature using titanium tetraisopropoxide (TTIP) and iron (III) chloride as a precursor.
In this research, Fe-doped TiO2 nanoparticles with various Fe concentrations (0, 1, 5 and 10 wt %) were prepared by a sol–gel method. Then, nanoparticles were characterized by X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDX) and FTIR. Degradation of 4-chlorophenol (4-CP) have been carried out at pH 3 with the percentage degradation of 90% under UV irradiation for 4 hours.
