Self‐Organized TiO 2 Nanotube Layers as Highly Efficient Photocatalysts

TiO2 anatase nanotube layers (see image) perform much better in the photocatalytic conversion of organic azo dyes than common photocatalysts. This is important for all self-cleaning applications and for cases where particle separation from the cleaned media is technologically expensive and difficult. Other potential applications of self-organized TiO2 nanotubular structures may arise based on the semiconductive properties of TiO2.
