Description

General description

Titanium dioxide (TiO₂, titania) is one of the most important materials having various important applications, such as water and air purification, self-cleaning materials and photovoltaic cells. TiO₂ is an n-type semiconductor having a wide band gap (3.2eV for anatase and 3.0eV for rutile). Deposition of thin films of TiO₂ doped with Mn on F-doped SnO2-coated glass by spin coating has been described. Deposition of thin films of titanium dioxide (TiO₂) on various substrates by a simple sol-gel dip coating technique has been proposed. It has various photocatalytic applications where it can be used in two forms, i.e as highly dispersed fine particles on porous support materials and as suspended fluids in liquid medium.
Titanium(IV) oxide is a white colored compound, which can be used as a coloring pigment in paints and a main ingredient of cosmetics and toothpaste. It can be prepared via reaction of titanium(IV) chloride with oxygen gas. It can also find applications in photovoltaics, photocatalysis and gas sensors.
