The ILs-assisted electrochemical synthesis of TiO 2 nanotubes: The effect of ionic liquids on morphology and photoactivity

Visible‐Light Photocatalytic Activity of Ionic Liquid TiO2 Spheres: Effect of the Ionic Liquid's Anion Structure

“…It was shown that ILs can form protective layers owing to steric hindrance, electrostatic interactions, solvation forces, and viscous stabilization . ILs can act as structuring agents or soft templates, providing nano‐ and microstructures with uniform sizes and distributions, controlled morphologies, and, as a consequence, desired and improved properties . Moreover, changes in the physicochemical properties of ILs induced by confinement in nanoporous oxide matrices were also investigated…”

Hydrothermal in situ synthesis of Rb and S co-doped Ti-based TiO2 sheet with a thin film showing high photocatalytic activities

“…When H 2 O 2 is added to the system (Fig. 9b), according to K} orösi et al, 48 additional cOH and cO 2 À are formed following eqn (6) and (7). Compared with the system without H 2 O 2 , in the system with H 2 O 2 , the excess radicals increase the oxidation capacity, leading to better degradation efficiency.…”

“…1,2 Titanium dioxide (TiO 2 ) is a type of semiconductor material, which has aroused wide research interest because of its nontoxicity, low cost, excellent thermal and chemical stability, strong optical absorption, and great electronic and catalytic properties. [3][4][5] It is one of the most familiar semiconductor photocatalysts for the degradation of organic pollutants, [6][7][8] the manufacture of dye-sensitized solar cells, 9 the photocatalytic hydrogen generation, 10,11 and so on. However, due to the large band gap of TiO 2 (3.2 eV), 12,13 only when the wavelengths of the light are less than 400 nm, the electron-hole pairs would appear.…”

Impact of the anodization time on the photocatalytic activity of TiO2 nanotubes

“…This last emission peak is within the range of signals connected to interstitial N, (O–N • –Ti), and has been associated with electron transitions from Ti 3+ /oxygen vacancy centers to interstitial N atoms [35,37–39]. These substitutional N atoms can also be associated with the enhanced signal in the OH group band (531.5 eV) [40–41]. These observations are relevant to our study since the presence of both F and N signals suggests a co-doping effect, as shown in Figure S1a (Supporting Information File 1).…”
