TiO 2 nanotube layers possess a wide range of applications for energy conversion, environmental clean‐up, and biomedical implant materials. The formation process of these tube layers is based on a simple but highly optimized anodization process of Ti in a suitable solution. The present work gives a coherent overview on the effect of the key parameters to grow these tube layers. The influence of fluoride content, anodization voltage, water content, and temperature on tube morphology is shown and discussed. The results thus provide the reader with “recipes” and understanding to grow desired TiO 2 nanotube structures, as well as show current limits and open room for improvement for the tailored growth of these structures.
