Summary: The present study synthesized Bismuth ferrite embedded TiO2 (BFO/TiO2) nanocomposites and demonstrated their promising application in the photocatalytic treatment of industrial effluents. The BFO/TiO2 nanocomposites showed good photocatalytic activity under visible and solar light, degrading various dyes in a mixed dye aqueous solution. The nanocomposites proved to be superior to BFO or TiO2 nanoparticles in terms of visible light activity.

Summary: The study indicated that tetraalkylammonium bromide surfactants significantly enhance the efficiency of TiO2 photocatalytic degradation of dyes, with various factors such as initial pH, dye pK's, water type, and light source influencing the process. The hydrophobic and electrostatic interactions between dye and surfactant/TiO2 in different forms of aggregation play a crucial role in explaining the surfactant effect on the photodegradation process.

Summary: The study established the influence of the crystalline phase and agglomeration degree of TiO2 nanoparticles on photocatalytic hydroxyl radical formation and bacterial inactivation in TiO2/SiO2 composite coatings. A relationship between hydroxyl radicals' formation and charge carrier transfer mechanism between defect levels in SiO2 and TiO2 embedded nanoparticles was established through a simple spectroscopic method. This correlation complements the lack of mechanisms behind the photocatalytic activity in TiO2/SiO2 composites.

Summary: A tunable band structure W-doped TiO2 photocatalyst was designed for the photocatalytic oxidation of methane to C-1 oxygenates using O-2 at low temperature. The W-doping improved the photocatalytic performance, achieving a liquid oxygenates productivity of 12.2 mmol g(-1) and a selectivity of 99.4%. Additionally, the selectivity of COx was effectively decreased from 21.2% to 0.6%. W-doping not only enhanced light absorption but also promoted the separation of photo-generated carriers, improving methane conversion.

Summary: This study aims to improve the performance of a UV-C disinfection unit by embedding supported photocatalysts in the system. The results show that the spray-coated composite material efficiently removes methylene blue within 30 minutes. The composite material containing both low and high tungsten loadings shows the most promising results in a commercial UV-C flow reactor. This study also demonstrates that embedding photocatalytic fiber can decolorize dyes while maintaining the disinfection effect on Escherichia coli.

Summary: This study presents the characteristics of saccharose-modified TiO2 photocatalysts obtained through a low-temperature hydrothermal method. The influence of these photocatalysts on the survivability and enzyme activity of Escherichia coli and Staphylococcus epidermidis under UV-A and artificial solar light was examined. The TiO2-1%-S-100 photocatalysts were capable of achieving complete inactivation of the bacteria under artificial solar light irradiation in less than 1 hour. The study also discusses the impacts of sugars on the photocatalytic activity and disinfection performance.

Summary: The study demonstrates that marine phytoplankton are more sensitive to iron content in solid particles, especially ilmenite and hematite which have a positive impact on the growth of diatoms. Diatoms acquire iron from solid particles, with smaller growth responses when physically separated from dust particles. Additionally, diatoms benefit more from mineral dust particles in direct contact with cells.

Summary: UV treatments are commonly used for pollutant removal in industrial water. Introducing a suitable photocatalyst can enhance energy efficiency by producing reactive oxygen species to degrade pollutants. TiO2 is a common photocatalyst for UV illumination, often created through Plasma Electrolytic Oxidation (PEO) of titanium substrates. High surface roughness and area on PEO samples enhance photocatalytic activity by disrupting fluid flow and increasing interaction between pollutants and the catalytic surface.

Summary: Porphyrins have been widely used as photosensitizers in the field of photovoltaics and photocatalysis due to their ability to transfer energy from light-collecting areas to reaction centers, similar to natural photosynthesis. However, while solar cell development has led to continuous improvement in the molecular design of these pigments, these innovations have not been efficiently applied to dye-sensitized photocatalysis. This review aims to explore recent advances in the role of porphyrin structural motifs as sensitizers in TiO2-mediated catalysis, providing valuable insights for the development of more efficient photocatalysts.
