Coprecipitation synthesis of fe-doped TiO2 from various commercial TiO2 for photocatalytic reaction.

Int. J. Environ. Res. 14, 605–613 (2020)
DOI
The current work reports the synthesis of Fe-doped TiO(2)nanoparticles by simple coprecipitation method and compares their photocatalytic efficiency to three different commercially available TiO2(i.e., Sachtopore, Hombikat UV100 and Fluka) using methyl orange (MO) under UV light irradiation. X-ray diffraction (XRD), diffuse reflectance spectroscopy (DRS) and transmission electron microscopy (TEM) were used to characterize these synthesized Fe-doped TiO(2)nanoparticles. In fact, the DRS results revealed that the bandgap of doped photocatalysts is smaller compared to undoped TiO2, leading to a slight shift in the absorption band towards the beginning of the visible light. In addition, XRD has shown that all samples were well crystallized and have only anatase phase. Accordingly, the photocatalytic investigation revealed that doped TiO(2)exhibited improved photocatalytic efficiency of methyl orange (MO) compared to undoped TiO(2)photocatalysts and depends on iron constituents, TiO(2)types as well as the doses of synthesized nanomaterials.
