Final Report Summary - TI- NANOTUBES (Preparation, characterisation and application of self-organised titanium oxide - nanotubes)
The project achieved in doping TiO2 with silver (Ag) as well as with iron (Fe). The Ag- and Fe-modified nanotube arrays exhibited an enhanced photocatalytic activity, therefore, enabling possible the solar energy conversion applications. TiO2 nanotubes have been created on sputtered Ti substrates and RBS provided further information regarding the oxide production efficiency, while RBS and NRA demonstrated the composition of nanotubes, namely the presence of fluorine as well as carbon contaminants of titania. Furthermore, a polarised micro-Raman investigation has been performed in order to study the phase composition, the finite size, the orientation and antenna effects of self-assembled anodised TiO2 nanotube arrays. Finally, the project proceeded with the characterisation of Ti-nanotubes, with photo-induced applications as well as with several efficient solar energy conversion related applications.
