Summary: This study systematically investigated the modification of anatase TiO2 with tungsten and its impact on phase transition temperature and photocatalytic degradation of 1,4-dioxane. It was found that 8 mol. % W was the optimum loading for the development of high temperature stable anatase WTiO2 composite photocatalysts. The photocatalytic activity was significantly affected by the anatase content, with 8-W-TiO2 showing the highest degradation rate for 1,4-dioxane.

Summary: This study aims to clarify the differences between titanium dioxide polymorphs and their properties in different photocatalytic applications. Homophase titanium dioxide has disadvantages such as high recombination rates and low adsorption capacity. On the other hand, heterophase titanium dioxide can effectively stimulate electron transfer and exhibit superior photocatalytic performance. Various biphase and triphase polymorphs of titanium dioxide are discussed, and the focus is on the synthesis and application of heterophase titanium dioxide as a photocatalyst.

Summary: Reduction of TiO2 has been studied under different conditions. The addition of ammonia solution followed by hydrothermal treatment and calcination in Ar resulted in the formation of surface defects such as hole traps and oxygen vacancies in the reduced TiO2. Heat-treatment under hydrogen gas produced the highest amount of reduced Ti3+ centers, leading to improved water splitting and enhanced photocatalytic properties. Hydrogen was found to be a stronger reducing agent than ammonia gas.

Summary: A single-step impregnation approach was used to prepare TiO2-based photocatalysts with high degradation rates towards methylene blue (MB) under visible light. The photocatalysts were prepared using nitrate precursor compounds for copper and silver, namely Ag/TiO2 and Cu/TiO2 photocatalysts. The physicochemical properties of the catalysts were determined by XRF, BET, and XRD analysis, while the metal nature, titania matrix effect, metal concentration parameters, and catalyst concentration in the MB solution were investigated.

Summary: The low-temperature synthesis of TiO2 nanocomposites allows precise tuning of the anatase/rutile ratio. Different phase compositions have varying impacts on water oxidation, hydrogen peroxide reduction, and water reduction reactions, with the A series showing higher activity in oxidation-controlled reactions and the B series facilitating reduction-controlled processes. The design of optimal photocatalysts should consider both intrinsic and extrinsic factors for improved catalytic activity.

Summary: Ag-TiO2-x nanocomposites were fabricated by Ag+ ion exchange, exhibiting strong visible-light absorption and hot electron generation. The introduction of Ag nanoparticles led to the formation of anatase-rutile heterojunction and narrowed the bandgap, facilitating the photocatalytic reduction of Cr (VI) under visible light. The synergistic effect of Ti3+ defect energy level, anatase-rutile heterojunction, and SPR effect of Ag nanoparticles was proposed as the photocatalytic reduction mechanism.

Summary: In this study, the interrelation between crystallinity, surface hydroxylation, and electronic structure in titania nanoparticles (NPs) was investigated using density functional theory-based calculations. The results showed that the local coordination environments of the atoms in annealed non-crystalline NPs became similar to those in faceted crystalline anatase NPs with increasing hydroxylation. Highly hydroxylated annealed NPs also exhibited similar electronic energy gaps and band edge orbital characters to crystalline anatase NPs. These findings suggest that the anatase crystal structure may not be essential for TiO2 NP applications, and crystal-like NPs could exist in other nanomaterials.

Summary: Facet-dependent toxic metal adsorption of iron oxides can be influenced by organic acids, but the coadsorption mechanisms of specific facets are not fully understood. This study investigated the Cr(VI) adsorption onto lepidocrocite-exposed facets in the presence of oxalic acid and found that the adsorption capacity differed between rod-like lepidocrocite and plate-like lepidocrocite. The competitive adsorption processes between oxalic acid and Cr(VI) showed facet dependence and were determined by the interfacial interactions and geochemical behaviors of Cr(VI) in polluted environments.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
