Summary: The study presents porous carbon-doped anatase TiOx (C-TiOx) nanosheets with high-concentration active sites of Ti3+ obtained through a reproducible bottom-up approach. It demonstrates that the high-concentration Ti3+ sites play a vital role in enhancing N-2 photoreduction activity. Combined with the morphology of porous nanosheets and the loading of a Ru/RuO2 cocatalyst, the optimized C-TiOx shows a high NH3 production rate and remarkable quantum efficiency under visible-light irradiation, outperforming current TiO2-based photocatalysts.

Summary: Efficient visible light photocatalytic elimination of pharmaceutical factory wastewater was achieved by introducing hybrid Ag/AgCl nanoparticles into Ti3+ self-doped TiO2 mesocrystals. The Ag/AgCl@Ti3+-TiO2 mesocrystals showed superior performance in degrading tetracycline under visible light, mainly attributed to the continuous attacks of photo-generated holes and radicals on tetracycline molecules.

Summary: Ultrathin TiO2 nanosheets containing Ti3+ sites were used as a photocatalyst to degrade enrofloxacin (ENR) under visible light with a high efficiency of 98.6%. The higher degradation efficiency of ENR over NST is attributed to the increased Ti3+ and oxygen vacancies (OVs). Ti3+ sites on NST can form surface coordination intermediates with ENR molecules, activating ENR. The OVs on NST can adsorb and activate more O2 molecules, accelerating the generation of O2- by photogenerated electrons reduction. The photogenerated holes quickly transfer to the catalyst surface to directly degrade the activated ENR. A mechanism is proposed to explain the synergistic effect of coordination activation and photocatalysis over NST at a molecular level. This study emphasizes the important role of coordination activation in the photocatalytic degradation of antibiotics.

Summary: Self-doped Ti3+-TiO2 and amorphous ZnS layers-coated Ti3+-TiO2 nanostructures were successfully synthesized for organic pollutant degradation under visible-light illumination. The Ti3+-TiO2 clusters exhibited efficient visible-light absorption and photocatalytic performance, while the amorphous ZnS layers greatly enhanced the charge separation between ZnS layers and self-doped Ti3+-TiO2 clusters. The Ti3+-TiO2@ZnS-15% heterojunction showed the highest photocatalytic activity, approximately 9.87 times that of commercial TiO2, and also exhibited enhanced performance in degrading ciprofloxacin and tetracycline under visible-light illumination.
