“…The micrograph of the Fe-TiO 2 sample indicates the existence of small spherical particles similar to those observed for parent titania, in addition to various irregular particle agglomeration that results from the incorporation of Fe ions into titania structure. These results are in agreement and supported by other studies (Ahmed et al 2013;Khasawneh et al 2021).…”

“…broadening on the high BE side. According to the literature, the peak at 529.3 eV was ascribed to lattice oxygen in Fe-Ti oxides (Khasawneh et al 2021;Visentin et al 2011). On the other hand, the shoulder at 531.7 eV could be associated to oxygen of the defective -OH groups (Palanisamy et al 2013).…”

“…Results show the improvement in the photoactivity of Fe-TiO 2 compared with bare TiO 2 thin film with a thickness of 6.30 ± 0.04 µm. According to the literature, the presence of Fe 3+ prevents the electron-hole recombination and promotes the generation of hydroxyl radicals (Khasawneh et al 2021;Mesgari et al 2012;Mohamed et al 2019), and both effects contribute to improve the photoactivity of the doped material.…”

“…Moreover, Fe 3+ is involved in the separation of photo-generated h + /e − pairs which is due to the energy level of Fe 3+ /Fe 2+ which is below the conduction band edge of TiO 2 ; the Fe 3+ can trap the photo-generated electrons. Altogether, Fe 3+ traps the photogenerated holes (h + ) due to the energy level of Fe 4+ /Fe 3+ which is above the valence band edge of titanium dioxide (Khasawneh et al 2021).…”

“…For that reason, in recent years, researchers have developed a variety of treatment methods, including biological, physical, and chemical oxidation to remove trace sulphonamide antibiotics from water environment (Wang et al 2020). However, the photodegradation of pharmaceutical compounds (e.g., SMT) using Fe 2 O 3 -TiO 2 photocatalyst was rarely investigated in the literature (Khasawneh et al 2021), and no studies using Fe 2 O 3 -TiO 2 thin film has been developed to our knowledge. Thus, in this work, we attempt to fill the research gap and contribute towards investigating the solar photocatalytic degradation of pharmaceuticals using Fe 3+ -TiO 2 thin films.…”

Fe3+-TiO2 (Fe-TiO2) thin films were successfully prepared using a “sandwich” approach. TiO2 NPs were doped with different Fe3+ content (0.05%, 0.1%, 0.2% molar ratio), and the modified TiO2 NPs were deposited on glass flat support by dip coating.Structural, morphological, optical, and photocatalytic properties of Fe-TiO2 thin films were studied. XPS spectra confirm the presence of Ti, Fe, O, and defective –OH groups at the material surface. The Fe 2p spectrum demonstrates the existence of Fe3+. SEM images indicate that the incorporation of Fe3+ deforms in some degree the homogeneity of the TiO2 system. Additionally, incorporation of Fe3+ ions to the network creates an impurity band near the VB due to the oxygen vacancies, resulting in the reduction of the effective optical band gap. Photocatalytic activity of fabricated thin films in the elimination of sulfamethoxazole (SMT) follows pseudo first-order kinetics. The highest SMT removal yields were achieved using the sample with 0.05%Fe. Additionally, the use of greater thicknesses improves the removal performance. However, material detachment limits the maximum usable value around 6 µm.Finally, stability and reusability of catalysts were confirmed studying the photocatalytic activity over three cycles and evaluating that no Fe3+ leaching occurred.

Titanium dioxide (TiO2) stands out as a versatile transition‐metal oxide with applications ranging from energy conversion/storage and environmental remediation to sensors and optoelectronics. While extensively researched for these emerging applications, TiO2 has also achieved commercial success in various fields including paints, inks, pharmaceuticals, food additives, and advanced medicine. Thanks to the tunability of their structural, morphological, optical, and electronic characteristics, TiO2 nanomaterials are among the most researched engineering materials. Besides these inherent advantages, the low cost, low toxicity, and biocompatibility of TiO2 nanomaterials position them as a sustainable choice of functional materials for energy conversion. Although TiO2 is a classical photocatalyst well‐known for its structural stability and high surface activity, TiO2‐based photocatalysis is still an active area of research particularly in the context of catalyzing artificial photosynthesis. In this review, we provide a comprehensive overview of the latest developments and emerging trends in TiO2 heterostructures and hybrids for artificial photosynthesis. We begin by discussing the common synthesis methods for TiO2 nanomaterials, including hydrothermal synthesis and sol‐gel synthesis. We then delve into TiO2 nanomaterials and their photocatalytic mechanisms, highlighting the key advancements that have been made in recent years. We discuss the strategies to enhance the photocatalytic efficiency of TiO2, including surface modification, doping modulation, heterojunction construction, and synergy of composite materials, with a specific emphasis on their applications in artificial photosynthesis. TiO2‐based heterostructures and hybrids present exciting opportunities for catalyzing solar fuel production, organic degradation, and CO2 reduction via artificial photosynthesis. This review offers an overview of the latest trends and advancements, while also highlighting the ongoing challenges and prospects for future developments in this classical yet rapidly evolving field.This article is protected by copyright.

In conventional wastewater treatment plants, micropollutants mix with the aquatic environment because they cannot be removed entirely due to their nonbiodegradable structure. Advanced oxidation processes can be considered an alternative solution to this problem. In this study, five different pharmaceutical and personal care products, carbamazepine, diclofenac, ibuprofen, paracetamol, and triclosan, which are commonly found in aquatic environments, were selected as target pollutants. The removal of these target pollutants was investigated using advanced oxidation methods such as the Fenton and UV processes (UV, UV/H2O2, and UV/TiO2). The feasibility of processes in terms of cost was investigated. In the study, both initial and final pharmaceutical concentrations were measured using liquid chromatography mass spectrometry/mass spectrometry to accurately calculate removal efficiency. It has been determined that processes other than the UV process have removal efficiency >99.9%. The UV process showed removal efficiency of 40% for carbamazepine, 90% for diclofenac, 85% for ibuprofen, 86% for paracetamol and 85% for triclosan. Among the processes with high removal efficiency, the Fenton process has been integrated into wastewater treatment plants and has been shown to be the most suitable system in terms of both performance and cost in solving the micropollutant problem.
