Summary: This study compared the photocatalytic performance of nano-sized nitrogen-doped titanium oxide (N-TiO2) and tourmaline-nitrogen-co-doped titanium oxide (T-N-TiO2) for inactivation of pathogens under visible light irradiation, using Staphylococcus aureus as a model pathogen. The results showed that the photocatalyst dosage, initial microbial concentration, and visible light intensity are key factors affecting the photocatalytic inactivation process for both photocatalysts. Additionally, T-N-TiO2 exhibited better inactivation efficiency for various pathogens compared to N-TiO2.

The unique energy input of this technology enables the synthesis, crystallization, doping, and porosity of TiO2 within minutes. The resulting N-TiO2 demonstrates a nanoporous structure with doped N atoms, which leads to narrow bandgap, effective charge-carrier separation, and enhanced light absorbing ability. The N-TiO2 photocatalysts exhibit efficient photocatalytic activities and excellent antibacterial ability, making them suitable for environmental and biomedical applications.

Summary: This study investigates the effect of catalyst's surface Fe site and oxygen defect on the photo-Fenton reaction by using in-situ iron ions doped titanium dioxide meso-crystals as a model. The in-situ doping strategy anchors Fe ions on the surface of meso-crystals through oxygen vacancies, promoting the circulation of Fe3+/Fe2+ and enhancing the separation efficiency of photogenerated carriers. The interaction between oxygen vacancies and Fe ions improves the synergy between photocatalysis and Fenton reaction. The study demonstrates the efficient degradation of organic pollutants and mineralized intermediates under visible light irradiation, providing a potential path to prepare efficient visible light photo-Fenton catalysts.

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.
