In the past decade, anodically formed self-organized TiO2 nanotube layers attracted considerable scientific interest (see e.g. reviews [1,2]). This is mainly due to the fact that these layers combine the defined nanotubular geometry with a broad range of functional features inherent to TiO2. Particularly in photoelectrochemical and photocatalytic applications nanotubular layers have shown remarkable results.

In this work, we compare composition, structure and morphology of the tube layers using depth profiling techniques (GDOES, TOF-SIMS), sectioning techniques (ion milling), TEM, and integral methods (thermal desorption), to achieve an understanding of how key functional features are and can be embedded in TiO2nanotube arrays.
