What is it about?

The bare metallic titanium obtained from industrial waste materials was used, in a nobel simple procedure, to obtain anatase photocatalytic nanometric particles of about 4 nm in size. In the synthesis process, the formation of NH4TiOF3 was identified in the same shape of nanotubes that usually are obtained by anodizing titanium. The fluor in this compound reacted slowly with water transforming the nanotubes into nanoparticles.

Why is it important?

The anatase is a crystalline form of titanium oxide, which is photocatalytic and by UV illumination such as that of sunlight can cause redox reactions capable of splitting water and decomposing toxic organic molecules not only in water by also in air.


The anatase has a permanent photocatalytic activity as long as being illuminated by UV light. Its potential use for water and air cleaning has been extensively investigated and finding new procedures such as this one, is very unusual. Nevertheless, this kind of procedure may lead to use it in many applications to solve real environmental problems.
