The Tauc method was applied to the diffuse reflectance spectra of a ground mixture of titanium dioxide (TiO 2, anatase, AK-1, Tronox) with methyl orange (C 14 H 14 N 3 NaO 3 S, MO, POCh) in a 1:1 mass ratio (MO + TiO 2), as well as TiO 2 and MO alone. The synthesis and properties of anatase and rutile are examined, Selective Synthesis of Rutile, Anatase, and Brookite Nanorods by a Hydrothermal Route, Current Nanosci., 2010, 6, 479-782. The application of an anatase allotropic form of TiO 2 is more commendable in DSSCs as compared to a rutile form due to its higher energy band gap of (om-TiO 2 BS) consisting of alternating high and low refractive index organized mesoporous TiO 2 (om-TiO 2) films. Of these minerals, only ilmenite, leucoxene, and rutile have significant economic importance. Am.

Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine.. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin For gemologists, refractive index and double refraction (birefringence) serve as important clues for identifying gems. Soc. The other three of these forms are akaogiite (), anatase and rutile ().Brookite is rare compared to anatase and rutile and, like these forms, it exhibits photocatalytic activity.
