Editing Titanium dioxide (section)

===Specialized methods===
For specialty applications, TiO<sub>2</sub> films are prepared by various specialized chemistries.<ref>{{cite journal |title=Titanium Dioxide Nanomaterials: Synthesis, Properties, Modifications, and Applications|author1=Chen, Xiaobo |author2=Mao, Samuel S. |journal=Chemical Reviews|year=2007|volume=107|issue=7|pages=2891–2959|doi=10.1021/cr0500535|pmid=17590053}}</ref> Sol-gel routes involve the hydrolysis of titanium [[alkoxide]]s such as [[titanium ethoxide]]:

: Ti(OEt)<sub>4</sub> + 2 H<sub>2</sub>O → TiO<sub>2</sub> + 4 EtOH

A related approach that also relies on molecular precursors involves [[chemical vapor deposition]]. In this method, the alkoxide is volatilized and then decomposed on contact with a hot surface:

: Ti(OEt)<sub>4</sub> → TiO<sub>2</sub> + 2 Et<sub>2</sub>O
