Titanium dioxide (TiO2, titania) is one of the most important materials having various significant applications, such as water and air purification, self-cleaning materials and photovoltaic cells. TiO2 is an n-type semiconductor having a wide band gap (3.2 eV for anatase and 3.0 eV 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 coloured compound, which can be used as a colouring 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 photovolta
