Self organized TiO2 nanotubes/nanopores by anodization


The growth of high aspect ratio TiO2 nanotubes is achieved by electrochemical anodization in different electrolytes. Under ideal conditions, the growth of the pores is completely self-organized. The growth mechanism and feasibility to modify the dimensions of the pores are currently under investigation. The specific properties of TiO2, such as catalysis (self-cleaning), sensing, changes of wettability under UV illumination or solar energy conversion, can be exploit here in a nanotube form due to extremely high surface area.
