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.[1] 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.[2]
Titanium(IV) oxide is a white colored compound, which can be used as a coloring pigment[3] in paints and a main ingredient of cosmetics and toothpaste.[4] It can be prepared via reaction of titanium(IV) chloride with oxygen gas.[3] It can also find applications in photovoltaics, photocatalysis and gas sensors.[5]
