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.

Summary: In this study, nitrogen-doped titanium dioxide/boron-doped diamond heterojunction (N-TiO2/BDD) was proposed as an effective approach to improve the catalytic activity. The N-TiO2/BDD heterojunction showed enhanced photoelectrochemical (PEC) activity compared to TiO2/BDD, with extended absorption spectrum and higher electrical conductivity. The performance of N-TiO2/BDD was influenced by doping concentration and bias potential. Under optimized conditions, the N-TiO2/BDD heterojunction achieved a larger current density and demonstrated promising applications in organic pollutant treatment.

Summary: Photocatalytic nitrogen fixation to ammonia and nitrates is a promising sustainable route. This study modified the TiO2 framework via aliovalent molybdenum doping to enhance the photocatalytic performance. Aqueous-dispersed colloidal semiconductor nanocrystals (NCs) with precise morphological control and better carrier mobility were used. The Mo-TiO2 NCs functionalized with charged hydroxyl groups showed simultaneous production of ammonia, nitrites, and nitrates in water. Mo-doping and nanostructuration significantly improved the overall N-2 fixation performance.

Summary: The room-temperature nitrogen reduction reaction (NRR) has great importance in the fertilizer industry and fundamental catalysis science. This study demonstrates the knowledge-driven design of boron-doped TiO2 as a photocatalyst for NRR. Among 54 catalysts, boron-doped anatase TiO2(101) is identified as an exceptional NRR catalyst with strong visible-light absorption and excellent reactivity. Experimental validation shows that B-doped TiO2 nanosheet achieves high ammonia production under simulated sunlight, renewing the performance record for Ti-based photocatalysts for NRR. This work highlights the importance of dual active site catalysts for nitrogen activation and reduction and demonstrates the capacity of knowledge-driven catalyst design.

Summary: The synthesis of N-doped TiO2 film with co-exposed {101} and {111} facets via a one-pot facile hydrothermal method has been found to enhance the photocatalytic activity of TiO2. The incorporation of N ions into TiO2, as confirmed by high-resolution transmission electron microscopy (HR-TEM) and X-ray photoelectron spectroscopy (XPS), results in facet modification. The bandgap of N-doped TiO2 photocatalyst shifts towards a higher wavelength, indicating a reduction in TiO2 bandgap. Utilizing N-doped TiO2 as an active photocatalyst, up to 66% methylene blue has been successfully degraded. The enhanced photodegradation of N-doped TiO2 film is mainly attributed to the presence of {101} and {111} facets, facilitating efficient carrier separation and prolonging the lifetime of photogenerated carriers, thereby improving its photocatalytic potential.
