Nanocrystalline TiO₂ Composite Films for the Photodegradation of Formaldehyde and Oxytetracycline under Visible Light Irradiation.
In order to effectively photodegradate organic pollutants, ZnO composite and Co-B codoped TiO₂ films were successfully deposited on glass substrates via a modified sol-gel method and a controllable dip-coating technique. Combining with UV-Vis diffuse reflectance spectroscopy (DRS) and photoluminescence spectra (PL) analyses, the multi-modification could not only extend the optical response of T...
متن کاملPhotocatalytic Degradation of Methylene Blue by Innovative BiVO4/TiO2 Composite Films under Visible Light Irradiation
Bismuth vanadate and titanium dioxide (BiVO4/TiO2) composites, used as visible-light-driven photocatalysts were successfully synthesized with different mole ratios by coupling of a co-precipitation method with a sol-gel method. The phase transitions of the as-prepared BiVO4/TiO2 composites were carried out by X-ray diffraction (XRD). The results clearly indicated that the as-synthesized BiVO4/T...
متن کاملPhotocatalytic degradation of methyl orange using TiO2:Mg2+/zeolite composite under visible light irradiation
Photodegradation of methyl orange was investigated using synthesized TiO2:Mg2+/zeolite as the photocatalyst. The photocatalyst was characterized by X-ray, XRF, FT-IR, and SEM. The photocatalytic activities of TiO2:Mg2+/zeolite samples were evaluated in the degradation of methyl orange under visible light irradiation. The appropriate content of Mg in the composite was obtained as 4.711 wt% with ...
متن کاملDetection of intermediates in the TiO2-assisted photodegradation of Rhodamine B under visible light irradiation.
The photocatalytic degradation of dye Rhodamine B (RhB) in the presence of TiO2 nanostripe or P25 under visible light irradiation was investigated. The degradation intermediates were identified using Infrared spectra (IR spectra), 1H nuclear magnetic resonance (1HNMR) spectra, and gas chromatography-mass spectroscopy (GC-MS). The IR and the 1HNMR results showed that the large conjugated chromop...
متن کاملPhotodegradation of dye pollutants on silica gel supported TiO2 particles under visible light irradiation
In this paper, silica gel supported titanium dioxide particles (TiO2/SiO2) prepared by acid-catalyzed sol–gel method was as photocatalyst in the degradation of acid orange 7 (AO7) in water under visible light irradiation. The particles were characterized by X-ray diffraction, BET specific surface area determination, and point of zero charge measurement. The supported catalyst had large surface ...
