Surface fluorination of single-phase TiO2 by thermal shock method for enhanced UV and visible light induced photocatalytic activity

Study of the effects of surface modification by thermal shock method on photocatalytic activity of TiO2 P25

“…Therefore, introducing defects on the surface of photocatalysts can be a feasible way to improve the photocatalytic activity. In our previous studies, fluorinated TiO 2 was successfully prepared by a simple thermal shock method [16,17]. This is the method which allowed us to carry out solid phase reactions at high temperatures during a short time.…”

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

“…Ti–OH groups act as electron traps that not only improve the separation efficiency for electron–hole pairs, but also improve the generation of free radicals that are responsible for the degradation of organic molecules. As the t a increased, the signal for surface OH groups was enhanced, suggesting a direct relationship with the fluorine content [34]. A third feature (O 1s III, 532 eV) was also present in the oxygen spectra and was ascribed to the presence of adsorbed water.…”

The Reaction Mechanism of Acetaldehyde Ammoximation to Its Oxime in the TS-1/H2O2 System

“…Because of the excess ammonia in the system, the solution was alkaline. However, in an alkalescent environment, hydroxylamine is extremely unstable, and it is easily decomposed into ammonia, nitrogen, nitrate and water [37][38][39][40]. After the addition of acetaldehyde in the second step, the hydroxylamine concentration decreased rapidly to a low value.…”
