Abstract :
Anatase and rutile-phase titania nanowires have been prepared via an efficient molten salt-assisted and novel pyrolysis route, respectively. The growth of anatase nanowires is parallel to [010] direction. The anatase titanium oxide nanowires are obtained by exchange reaction between Na2TiO3 and HCl, whereas the formation of rutile titania nanowires is conventional vapor–liquid–solid growth mechanism.
