High photocatalytic activity of mixed anatase-rutile ...

Whereas, the UV100 and the N100 are made up of anatase phase of TiO 2. The synergistic effect of the anatase/rutile mixture was reported to slow down the recombination rate of photogenerated electron-hole pairs. Consequently, the photocatalytic activity was increased on these TiO 2 nanoparticles.

Differences Between Rutile and Anatase Titanium Dioxide ...

Aug 15, 2012· Anatase is also used for the white pigmentation of paints, paper, and ceramics, but it is not advisable to use it outdoors because of its lower absorption rate than rutile. Summary: Titanium dioxide has two forms: rutile and anatase. Rutile is deep red while anatase is yellow to blue. Rutile has a high absorbance property than anatase.

Quantitative Analysis of Anatase-Rutile Mixtures with an X ...

largely anatase), the weight of R (98.7% Ti02, largely rutile), and the ratio of the intensity of the strongest anatase reflection to that of the strongest rutile reflection for the various sample mix- tures. The last two columns give the weight fraction of anatase and a func- tion of the intensity ratio that approxi-

Band Lineup and Charge Carrier Separation in Mixed Rutile ...

Calculations by the HSE06 functional for rutile and anatase crystals reproduce the observed width of the valence and conduction bands, as well as of the gap. From the band structures the branching point energies are obtained as reference for both phases, allowing us to deduce a generic band alignment scheme without a specific interface model.

A comparative study of the photocatalytic oxidation of ...

Oct 01, 2007· It is evident that surface species accumulate on all samples, but the mixed-phase anatase–rutile samples (P25 and own mix of anatase–rutile) have the highest conversion of propane to CO 2. Interestingly, the anatase sample exhibits the poorest initial total oxidation.

Nature of Rutile Nuclei in Anatase-to-Rutile Phase ...

The solid phase transition of TiO2, in particular anatase to rutile, has been extensively studied in the past 30 years. To seek the nucleation site at the beginning of phase transition is highly challenging, which asks for new theoretical techniques with high spatial and temporal resolution. This work reports the first evidence on the atomic structure of the nucleation sites in the TiO2 ...

Synergistic effect between anatase and rutile TiO ...

A synergistic effect between anatase and rutile TiO 2 is known, in which the addition of rutile can remarkably enhance the photocatalytic activity of anatase in the degradation of organic contaminants. In this study, mixed-phase TiO 2 nanocomposites consisting of anatase and rutile nanoparticles (NPs)

Titanium(IV) oxide, rutile | CAS 1317-80-2 | SCBT - Santa ...

Titanium(IV) oxide, rutile is a naturally occurring oxide of titanium, with the chemical formula TiO2. It is also known as titanium dioxide, it exists in 3 different chemical structures in nature (rutile, anatase, and brookite). Rutile is the most thermodynamically stable form of …

Mineral Classics - Pakistan Brookite, Anatase & Rutile

The Anatase specimens rival the quality of the finest Norwegian Anatase specimens for crystal size, color, luster and superb textbook form. The two reticulated "Sagenite" Rutile specimens remind me of pieces I've seen from the French Alps, so you've got a great mix of superb quality pieces that are top quality and would definitely excite Alpine ...

Rutile - digitalfire.com

Rutile is the mineral name for natural crystals of titanium dioxide. However in nature rutile is always contaminated by up to 15% other minerals (especially iron but also things like tantalum, niobium, chromium and tin, the analysis provided here is obviously a simplification of the real picture). The term 'rutile' is thus generally understood to refer to the brown powder into which these ...

Discrimination of the active crystalline phases in anatase ...

The active crystalline phases in powdered titanium(iv) oxide (TiO2) photocatalysts of anatase–rutile mixtures were investigated by measuring the action spectra of the photocatalytic reactions of H2 evolution, Ag deposition and acetic acid decomposition. All of the pure anatase …

Facile preparation of anatase–brookite–rutile mixed-phase ...

Phase mixing is the most promising strategy for quantum efficiency enhancement. A typical example is commercial Degussa P25, an anatase–rutile mixed-phase catalyst with anatase as an active component and rutile as an electron sink. P25 shows slower rates of recombination and thus higher photocatalytic activity than its pure phase counterparts.

Rutile Phase - an overview | ScienceDirect Topics

The formation of phase junctions between anatase and rutile TiO 2 provides a smooth path for photogenerated charge separation, which is regarded as the main factor for the highly photocatalytic activity of anatase and rutile mixed phased TiO 2 photocatalyst (Fig. 9 A).

Rutile - Wikipedia

Rutile is a mineral composed primarily of titanium dioxide (TiO 2), and is the most common natural form of TiO 2.Other rarer polymorphs of TiO 2 are known including anatase, akaogiite, and brookite.. Rutile has one of the highest refractive indices at visible wavelengths of any known crystal and also exhibits a particularly large birefringence and high dispersion.
