Controlled formation of anatase and rutile TiO2

We discuss the formation of TiO 2 thin films via DC reactive magnetron sputtering. The oxygen concentration during sputtering proved to be a crucial parameter with respect to the final film structure and properties. The initial deposition provided amorphous films that crystallise upon annealing to anatase or rutile, depending on the initial sputtering conditions.

Why is anatase a better photocatalyst than rutile?

Does a Photocatalytic Synergy in an Anatase–Rutile

However, in the case of dense thin‐films containing an intimate mix of both anatase and rutile phases, such an effect has not been observed. In synthesising combinatorial films with graded film thickness and phase, and applying established photocatalytic mapping methods, we were able to assess how dense thin‐films of intimately mixed anatase–rutile mixtures affect photocatalytic performance.

Preparation and Characterization of Pure Rutile

2.3. Preparation of Rutile TiO 2 Photoanodes and DSSC Performance Measurement. A doctor-blading technique was used to prepare the r-TiO 2 films on an FTO- (F-doped tin oxide-) coated conductive glass ( cm 3, Solaronix, sheet resistance 8 Ωcm −2) as DSSC photoanodes. Two edges of the FTO substrate were covered with Scotch tapes.

Refractive Index of TiO2 Rutile for Thin Film

Refractive Index of TiO2 Rutile Titanium dioxide (TiO2) is well-known for having a very high index of refraction, and this has led to its common use in thin-film optics. Typically, TiO2 is one component of alternating layers of high and low refractive index materials that by the principle of optical interference tailor the thin-film optic's spectral reflectance profile.

Photoemission Electron Microscopy of TiO2

Photoemission electron microscopy (PEEM) excited by X‐ray and UV sources is used to investigate epitaxial anatase thin films with embedded rutile nanocrystals, a model system for the study of heterocatalysis on mixed‐phase TiO 2.Both excitation sources show distinct contrast between the two TiO 2 phases; however, the contrast is reversed. Rutile nanocrystals appear darker than the anatase

Rutile Wikipedia

Rutile is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks.. Thermodynamically, rutile is the most stable polymorph of TiO 2 at all temperatures, exhibiting lower total free energy than metastable phases of anatase or brookite. Consequently, the transformation of the metastable TiO 2 polymorphs to rutile is irreversible.

When TiCl4 solution hydrolyzed in ice-water mixed DI water, rutile TiO2 can be prepared at a low temperature 70 °C, which is much lower than those of conventional Sol-Gel methods and hydrothermal process. XRD was carried out to analyze the crystal structure and
