| Summary: | Title screen The demand for potable water is currently one of the most critical challenges facing humanity. A promising solution for water purification, particularly for removal of pathogenic microorganisms, involves materials that exhibit both visible light–induced photochemical activity and antibacterial properties. These materials include composite systems based on TiO2/Ag composites. The present study introduces a novel method for modifying TiO2 with Ag nanoparticles through thermal fragmentation of silver in mixtures with TiO2 powder. Using this method, TiO2/Ag composites were produced with silver loadings of 1, 3, 5, and 10 wt. %. It was shown that, upon heating, silver undergoes fragmentation, forming nanoparticles 2–20 nm in size that coat the surface of the TiO2 particles. The resulting composites exhibit visible light photochemical activity and are capable of degrading methylene blue and Congo red dyes by 50% and 40%, respectively, within 1 h. The synthesized materials demonstrate 100% inactivation of S. aureus within 3 h of contact at a concentration of 100 μg/mL Текстовый файл AM_Agreement |
