In this article, patents and literature about the synthesis and potential applications of titania nanotubes for
photocatalytic and photovoltaic devices are presented. Oxidation of water by titania thin films was reported in 1972 for
the first time. In the following years, titania nanoparticles, nanorods and nanotubes have been intensively studied for this
and other potential applications. Potential applications for photochemical oxidation of water are in the areas of water
treatment for removing organic contaminants and microorganisms and hydrogen production. Other exciting potential
applications of titania nanotubes are in the generation of electric energy in solar cells, electric charge storage, and in coatings
for endoprosthesis. The considerably higher surface area of titania nanotubes compared with nanorods and nanoparticles
of the same size significantly increases the efficiency of devices based on titania nanotubes, especially for surface
controlled applications such as water oxidation and solar power generation.
