The characterization and photocatalytic properties of mesoporous rutile TiO2 powder synthesized through self-assembly of nano crystals

Preparation and characterization of novel Ti0.7W0.3O2–C composite materials for Pt-based anode electrocatalysts with enhanced CO tolerance

“…Moreover, various low temperature sol-gel based methods can be found in the literature for the preparation of pure rutile TiO 2 nanoparticles [16,[31][32][33][34][35]. Recently, an intense effort has also been devoted to loading TiO 2 on activated carbon using sol-gel technique [36][37][38][39].…”

Preparation of Nano-TiO<sub>2</sub> Thin Film Using Spin Coating Method

“…Similarly, the photocatalytic activity of nano-sized TiO 2 powders by sol-gel method, using Ti(OC 3 H 7 ) 4 (titanium isopropoxide ) and EtOH/H 2 O solution has been shown by [4] and the particle size obtained were 7.9 nm and 7.4 nm respectively. Likewise, [5] also studied the preparation and characterization of nano-TiO 2 powder by sol-gel method whose result yielded a mean size of about 10 nm after calcination. By similar method, the microstructure control of thermally stable TiO 2 obtained by hydrothermal process has been investigated by [6].…”

Ordered Mesoporous Thin Films of Rutile TiO2 Nanocrystals Mixed with Amorphous Ta2O5

“…One distinct work by Li et al reported the fabrication of mesoporous rutile powders by hydrolyzing TiOCl 2 aqueous solution at low temperatures in the presence of octyl poly(ethylene oxide) surfactant, which serves as template-directing agent. [13] This type of low-temperature-derived mesoporous rutile powder possessed high PA for the gasphase photooxidation of a mixture of benzene and methanol. [13] Evidently, such an approach seems to be unsuitable for the fabrication of thin films of mesoporous rutile, which would be an interesting complement to the corresponding anatase films.…”

[13] Evidently, such an approach seems to be unsuitable for the fabrication of thin films of mesoporous rutile, which would be an interesting complement to the corresponding anatase films. One of the difficulties in preparing mesostructured rutile using sol-gel templating is the fact that for nanocrystals with sizes below about 9 nm, [14] contrary to the bulk, anatase is thermodynamically more stable than rutile.…”
