Structural and optical properties of N-doped TiO2 nanomaterials

Improvement of low-temperature NH3-SCR catalytic performance over nitrogen-doped MOx–Cr2O3–La2O3/TiO2–N (M = Cu, Fe, Ce) catalysts

“…The crystal size increased in the following sequence: CeCrLa/TiO(OH) 2 < CeCrLa/TiO 2 < CeCrLa/TiO 2 –N < FeCrLa/TiO 2 –N < CuCrLa/TiO 2 –N. The different crystal size shows that N doping promotes the crystalline growth of anatase TiO 2 , 37 Fe, Cu and Ti oxide had interaction, and that the crystallite size increased in different extent.…”

Synthesis and Characterization of N and Fe-Doped TiO2 Nanoparticles for 2,4-Dimethylaniline Mineralization

“…The bands at 1650 cm −1 and 3200 cm −1 are associated with the O-H vibrational modes of adsorbed water. The N-doped photocatalysts present bands close to 1500 cm −1 and 3200 cm −1 , referring to the vibration of the N-H group [ 32 ]. The vibrational bands of the Fe-O bond are in the range of 400 to 700 cm −1 , but they were not observed due to the low concentration of iron used.…”

“…Jadhav et al synthesized N-doped TiO 2 doped with 25% N using urea as a precursor. The material synthesized by them degraded 70% of the methylene blue in 180 min of the experiment under visible light [ 32 ]. Synthesis using ammonium salt as precursor has also been reported and its photocatalytic activity showed a 90% removal in 40 min of rhodamine B [ 33 ].…”

Preparation of N-TiO2/SiO2 composites by solvothermal method and their photocatalytic properties

“…The catalytic activity of TiO 2 induced by metal doping modification can be attributed to the increase of the electron-hole complexation time [15]. In contrast, the modification of non-metallic elements enables visible response via narrowing the forbidden band width and expanding the corresponding range of visible light [16]. Hence, the non-metallic modified photocatalytic materials have higher visible light activity.…”
