“…These shifts demonstrate how photocatalytic activity may be modulated by atomic‐level doping of a nanocatalyst. The absorption wavelength of the 20N/SnO 2 /TiO 2 photocatalyst is extended toward visible light ( λ = 409.2 nm), relative to the other samples , giving it the highest photocatalytic activity. The N‐doping slightly decreased the band gap to 3.03 eV by formation of localized N 2p states just above the valence band maximum of TiO 2 , due to substitutional N species .…”

Photocatalytic degradation of glyphosate contaminated in water was investigated. The N-doped SnO2/TiO2 films were prepared via sol-gel method, and coated on glass fibers by dipping method. The effects of nitrogen doping on coating morphology, physical properties and glyphosate degradation rates were experimentally determined. Main variable was the concentration of nitrogen doping in range 0-40 mol%. Nitrogen doping results in shifting the absorption wavelengths and narrowing the band gap energy those lead to enhancement of photocatalytic performance. The near optimal 20N/SnO2/TiO2 composite thin film exhibited about two- and four-folds of glyphosate degradation rates compared to the undoped SnO2/TiO2 and TiO2 films when photocatalytic treatment were performed under UV and solar irradiations, respectively, due to its narrowest band gap energy (optical absorption wavelength shifting to visible light region) and smallest crystallite size influenced by N-doping.

“…Also, this peak was appeared at the same time when the new band appeared at around 1400 cm −1 which is associated with the bending vibration of CH group. Additionally, we can see the broad and strong peak at approximately 600 cm −1 , ascribed the absorption band of Ti-O and O-Ti-O flexural vibrations [35,36]. The VNR sample also exhibited the band at 970 cm −1 , assigned to C=CH deformation vibration [8].…”

“…The broad and strong peaks at 1630 to 1640 cm −1 are ascribed to the bending vibration of OH groups in free or adsorbed water . The larger surface hydroxyl group density will lead to enhancement of the photocatalytic activity and hydrophilic property since they can interact with photogenerated holes, which give better charge transfer and inhibit the recombination of electron‐hole pairs . The FTIR investigation confirms that surface OH group density of pure TiO 2 is lower than that of N‐doped TiO 2 , as they have the same specific surface area.…”

Pure titanium dioxide (TiO 2 ) and nitrogen (N)-doped TiO 2 nanorods array were prepared using polished Ti substrates and hydrothermal synthesis method. Prepared nanorods films were characterized by different techniques including X-ray diffractometer (XRD), field-emission scanning electron microscope, Fourier-transform infrared spectroscopy, and XPS. The photocatalytic activities of both prepared films were evaluated by their capacity to degrade methylene blue (MB) in solution, and an attempt to associate it with their surface wetting properties is achieved. The XRD results showed that the prepared TiO 2 is of rutile phase. Furthermore, the 3%N-doped TiO 2 nanorods films show similar high crystallinity and photocatalytic activity compared with prepared films of TiO 2 rutile phase. Additionally, their surface wetting properties were studied and showed hydrophobic behavior with contact angle higher than 120°. The hydrophobicity of 3%N-doped TiO 2 nanorod films is shown to be enhanced because of TiO 2 nanorods diameter decreasing. Additionally, the results clearly show that the prepared 3%N-doped TiO 2 nanorods films exhibit both higher hydrophobicity and the best photocatalytic activity toward the degradation of MB under visible light irradiation.
