Titanium Oxide TiO 2 Crystal Substrates - MSE Supplies LLC

High purity (>99.9%) Rutile TiO 2 single crystal substrates with epi-ready surface polish are widely used as substrate materials for thin film growth and depositions. Rutile phase Titanium Oxide (TiO 2) single crystal is one of the most commonly used materials for optical isolators and special prisms.This is because Rutile TiO 2 has a large birefringence with a high refractive index.

TiO 2 and TiO 2-based materials are prototypes for photo-catalytic reactions as they have been shown for many decades to be active for total oxidation of hydrocarbons to clean the environment. In the last decade or so there has been a shift in the objectives for photoreactions mainly towards hydrogen production from renewables. Here we review the fundamentals behind the reactivity of model TiO ...

Crystal Phase Effects on the Gas‐Phase Ketonization of ...

The choice of TiO 2 crystal phase (i. e., anatase, rutile, or brookite) greatly influences catalyst performance in the gas-phase ketonization of small volatile fatty acids, such as acetic acid and propionic acid.

Carbon-carbon bond formation on metal oxides: From single ...

Previous work in our laboratory indicated that carbonyl metathesis of aldehydes can be accomplished as a gas-solid reaction on a reduced TiO 2 (001) single crystal under ultrahigh vacuum (UHV). This reaction requires the presence of cations in lower oxidation states on the surface, but does not require Ti 0 as suggested by previous studies in the liquid phase.

Polyphenylene Oxide - an overview | ScienceDirect Topics

Titanium dioxide (TiO 2) is one of the most important pigments. It is widely used because it efficiently scatters visible and absorbs UV light, thereby imparting whiteness, brightness, and opacity when incorporated into a plastic. Titanium dioxide is commercially available in two crystal structures—anatase and rutile.

Photo-thermal reactions of ethanol over Ag/TiO2 catalysts ...

a recent work on TiO 2(110) rutile single crystals we have found similar results (CH 3 radical production from ethanol 23). This was not the case for anatase (101) single crystals. 24 TiO 2 P25 used in this work contains both phases; it is possible that CH 3 radical formation is predominantly linked to the rutile phase.
