Photocatalytic and Self-Cleaning Properties of Ag-Doped TiO2
Commercially available TiO2 of anatase structure produced in the Chemical Factory Police S.A. was modified by doping Ag from AgNO3 solution via photodeposition method. The obtained amount of deposited Ag on TiO2 was in the range of 0.11 to 0.98 mass %. Deposition of Ag on TiO2 resulted in the retarding of the recombination reaction and formation of the higher amount of OH radicals on the photoc...
متن کاملEffect Of Ag Doped On Phase Transformation, Morphology And Photocatalytic Activity Of TiO2 Powders
The purpose of this research was to study the effect of doped Ag on phase transformation, morphology and photocatalytic activity of TiO2 powders. The composites powders were prepared by sol-gel method via calcinations at a temperature 400 °C for 2 h with a heating rate of 10 °C/min. The microstructure and crystallite size of TiO2 and TiO2-Ag powders were characterized by XRD, EDX and SEM. Final...
متن کاملPhotocatalytic antibacterial performance of TiO2 and Ag-doped TiO2 against S. aureus. P. aeruginosa and E. coli
This paper reports the structural and optical properties and comparative photocatalytic activity of TiO2 and Ag-doped TiO2 nanoparticles against different bacterial strains under visible-light irradiation. The TiO2 and Ag-doped TiO2 photocatalysts were synthesized by acid catalyzed sol-gel technique and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-vis spe...
متن کاملAg-doped TiO2 Nanocomposite Prepared by Sol Gel Method: Photocatalytic Bactericidal Under Visible Light and Characterization
In this reaserch, photocatalyst titanium dioxide was doped with silver and modified by polyethylene glycol by sol gel method and the samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The purpose of the present study was to evaluate the photocatalytic bactericidal effects of prepared nanocomposite on human p...
متن کاملPhotocatalytic Antibacterial Performance of Glass Fibers Thin Film Coated with N-Doped SnO2/TiO2
Both N-doped and undoped thin films of 3SnO2/TiO2 composite were prepared, by sol-gel and dip-coating methods, and then calcined at 600 °C for 2 hours. The films were characterized by FTIR, XRD, UV-Vis, SEM, and XPS, and their photocatalytic activities to degrade methylene blue in solution were determined, expecting these activities to correlate with the inactivation of bacteria, which was conf...
