Structural Properties, Lattice Strain and Transformation of Anatase-Type TiO2 Nanocrystals to Rutile in TiO2-SiO2 Composite

Band alignment of rutile and anatase TiO2

The most widely used oxide for photocatalytic applications owing to its low cost and high activity is TiO2. The discovery of the photolysis of water on the surface of TiO2 in 19721 launched four decades of intensive research into the underlying chemical and physical processes involved2–5. Despite much collected evidence, a thoroughly convincing explanation of why mixed-phase samples of anatase ...

Synthesis and nano structural study on TiO2-NiO-SiO2 composite

We report on the synthesis, morphology, chemically and structurally of TiO2-NiO-SiO2 nanostructure. The TiO2-NiO-SiO2 nanostructure was synthesized by a method based on the sol-gel method, by the simultaneous gelation of all cations. The coatings were deposited on dried soda-lime glass slides by spin coating. Composite powders and coating on glass hav...

In situ characterization of the deposition of anatase TiO2 on rutile TiO2(110)

Dielectric and infrared properties of TiO2 films containing anatase and rutile

Electrical and optical properties of low-temperature, plasma enhanced chemical vapour deposited films of TiO2 have been studied; the source gases were TiCl4 and O2. The amorphous, as-deposited films had a dielectric constant ∼33 consistent with their measured density of 3.2 ± 0.2 g cm−3. Films deposited using a −41 V substrate bias contained the anatase phase and some rutile as evidenced from i...
