In this article, ferrous ferric oxide and Fe3O4-doped titanium dioxide have been synthesized by a low-temperature sol-gel process. In particular, we studied the structural characteristics of newly synthesized photosensitive catalysts and their photocatalytic abilities under UV and visible light irradiation. The elemental composition surface area, crystallinity, and morphology of synthesized catalysts were characterized by Fourier transformation infrared spectrophotometry, X-ray photoelectron spectroscopy, X-ray diffraction and transmision electron microscopy with selected area electron diffraction and energy-dispersive X-ray spectroscopy. The UV-vis transmission, zeta-potential, and cytoctoxicity of the synthesized catalysts are also discussed it is anticipated that the synthesized ferrous ferric oxide arrrays a prospective photocatalyst subsitute for titanium dioxide.
