“…Li et al [33] prepared the amorphous hcp TiO 2 nanocolumn arrays, which have better photocatalytic properties than anatase nanocolumn arrays. Our previous study also showed that amorphous TiO 2 sol had higher photocatalytic activity than anatase sol [34]. In this study, it was proven that thermal treatments can result in the formation of bulk TiO 2 and growth of TiO 2 molecules as confirmed by IR and Raman results, which decrease the dispersion of TiO 2 .…”

“…The broad adsorption band center at 3443 cm −1 is related to the stretch region of the surface hydroxyl groups with physisorbed and/or chemisorbed water[53][54][55][56]. The peak at around 1631 cm −1 is assigned to the deformation vibration for H-O-H bonds of physisorbed water[53][54][55][56].…”

“…In these spectra, the large and broad absorption peak near 3400 cm −1 is related to the stretch region of the surface hydroxyl groups with hydrogen bonds and chemisorbed water [30,31,32]. The absorption peak near 1630 cm −1 can be assigned to the O–H bending of molecularly physisorbed water [31,32].…”

Using ilmenite as a raw material, iron was converted into Fe3O4 magnetic fluid, which further was combined with titanium filtrate by a solvothermal method. Finally Fe3O4/TiO2 nanocomposites with the uniform size of 100–200 nm were prepared. This approach uses rich, inexpensive ilmenite as a titanium and iron source, which effectively reduces the production cost. The crystal structure, chemical properties and morphologies of the products were characterized by SEM, TEM, XRD, FTIR, BET, UV-Vis, XPS and VSM. The novel photocatalyst composed of face-centered cubic Fe3O4 and body-centered tetragonal anatase–TiO2 exhibits a spherical shape with porous structures, superparamagnetic behavior and strong absorption in the visible light range. Using the degradation reaction of Rhodamine B (RhB) to evaluate the photocatalytic performance, the results suggest that Fe3O4/TiO2 nanocomposites exhibit excellent photocatalytic activities and stability under visible light and solar light. Moreover, the magnetic titania nanocomposites displayed good magnetic response and were recoverable over several cycles. Based on the trapping experiments, the main active species in the photocatalytic reaction were confirmed and the possible photocatalytic mechanism of RhB with magnetic titania was proposed. The enhanced photocatalytic activity and stability, combined with excellent magnetic recoverability, make the prepared nanocomposite a potential candidate in wastewater purification.
