“…AR material is mainly composed of anatase (97%), accompanied with a small amount of rutile (3%), where mass fractions of anatase and rutile were determined from relative XRD diffraction intensities of [1 0 1] and [1 1 0] reflections for anatase and rutile, respectively, using Eqs. (3) and (4) [46]:…”

“…Microstructural characteristics (phase composition, particle size, specific surface area, porosity) of Degussa P25 powder are well-known, and described elsewhere [31][32][33]. For the sake of clarity, this data are presented in Table 1, together with data obtained for undoped and doped TiO 2 powders prepared by sol-gel synthetic route.…”

TiO 2 powders with different specific surface area were prepared using reproducible, sol-gel synthetic route and their ability to form hybrids with catechol and 5-amino salicylic acid was compared with the commercially available Degussa P25 TiO 2 powder. Microstructural characterization involving transmission electron microscopy, X-ray diffraction analysis and nitrogen adsorption-desorption isotherms indicated that TiO 2 samples cover reasonably wide size and/or specific surface area range (50-115 m 2 /g). The surface modification of TiO 2 powders with catechol and 5-amino salicylic acid induced significant shift of absorption to the visible spectral region due to charge transfer complex formation. It should be emphasized that tunable optical properties of TiO 2 in powder form have never been reported in the literature. The largest red M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 2 shift of the absorption onset was observed for sample with the largest specific surface area upon surface modification with both ligands. The binding of the modifier molecules to the surface Ti atoms was studied using Fourier transform infrared spectroscopy.

“…MIL-53 (Fe) was introduced to TiO 2 due to its high surface area property and its superior capability in photocatalysis. [31][32][33][34] XRD patterns of MIL-53 (Fe)/TiO 2 and calcined MIL-53(Fe)/TiO 2 show no typical peak for MIL-53(Fe) and MIL-53(Fe)-derived iron, respectively. The degradation data were fitted to the Langmuir-Hinshelwood kinetics model to understand the mode of heterogeneous photocatalysis.…”

Photocatalytic activity of titanium(IV) oxide (TiO2) can be enhanced through modification of its surface‐active sites. Here, iron(III) carboxylate [MIL‐53[Fe]]‐incorporated TiO2 (as MIL‐53(Fe)/TiO2) was prepared using a hydrothermal method. This material was then calcined at 500°C to obtain a MIL‐53(Fe)‐derived γ‐Fe2O3/TiO2 photocatalyst. A photocatalytic study of MIL‐53(Fe)/TiO2 and MIL‐53(Fe)‐derived γ‐Fe2O3/TiO2 toward cationic methylene blue (MB) and anionic methyl orange (MO) showed that MIL‐53(Fe)/TiO2 (0.25 wt%) and MIL‐53(Fe)‐derived γ‐Fe2O3/TiO2 (0.75 wt%) resulted the best degree of dye degradation. The MIL‐53(Fe)‐derived γ‐Fe2O3/TiO2 (0.75 wt%) composite for instance is capable of degrading almost 100% of 20‐ppm MB and MO, respectively, within 6 hr. Photocatalytic degradation of MB and MO was well fitted to the Langmuir‐Hinshelwood pseudo‐first order kinetics model, which indicates physisorption as the key partway that facilitates dye decomposition on the surface of a photocatalyst under UV‐A irradiation. This study provides new insights into the exploration of MILs/TiO2 materials for the environmental remediation and pollution control.
