Titanium dioxide (TiO 2) is one of the essential metal oxides in the interest of its vast number of applications due to its properties [1,2,3,4,5,6,7,8].It has three main phases: anatase, rutile, and brookite. Anatase and rutile are the most used in the industry, one for their catalytic properties and the other for their brightness [2, 3, 5, 8].TiO 2 …

Titanium dioxide exists in three phases: as rutile [ 1 ], anatase [ 1 ], and brookite [ 2 ]. These crystal phases assemble as octahedra, where six oxygen anions are …

During the past decade, research in the area of synthesis and applications of nanostructured titanium dioxide (NS TiO2) has become tremendous. NS TiO2 materials have shown great potential and a wide range of applications. The decrease in the particle size and the increase of the surface/volume ratio lead to the increase of the specific …

titanium dioxide either enhances or inhibits its reactivity, depending on the required application. Its recent exposure as a potential carcinogen to humans has been linked to controversies around titanium dioxide's toxicity; this is discussed by illustrating discrepancies between experimental pro-tocols of toxicity assays and their results.

Uses & Benefits. Pure titanium dioxide is a fine, white powder that provides a bright, white pigment.

Titanium dioxide (anatase), that is currently the most studied photocatalytic material, is a semiconductor with a bandgap of 3.2 eV. The absorption of photons having a higher energy than this bandgap causes the formation of a hole/electron couple. Holes of the valence band are strong oxidants (ranging from +1.0 to +3.5 V), while electrons of ...
