Synthesis and applications of nano-TiO2: a review

TiO 2 -based nanomaterials have attracted prodigious attention as a photocatalysts in numerous fields of applications. In this thematic issue, the mechanism behind the photocatalytic activity of nano-TiO 2 as well as the critical properties have been reviewed in details. The synthesis routes and the variables that affect the size and crystallinity of nano-TiO 2 have also been discussed in detail. Moreover, a newly emerged class of color TiO 2 , TiO 2 in aerogel form, nanotubes form, doped and undoped form, and other forms of TiO 2 have been discussed in details. Photocatalytic and photovoltaic applications and the type of nano-TiO 2 that is more suitable for these applications have been discussed in this review.
