Anodic formation of self-organized Ti(Nb,Sn) oxide nanotube arrays with tuneable aspect ratio and size distribution

• One-step anodization is used to prepare self-organized Ti(Nb,Sn) oxide nanotubes.
• Tunable nanoscale geometries can be achieved by varying the anodization conditions.
• The length and the diameter of the NTs tend to increase with the applied voltage.
• Combining TiO2 with NbO2 and SnO2 might provide additional functionalities.

In the present communication one-step anodization is used to prepare large arrays of self-assembled Ti(Nb,Sn) oxide nanotubes on Ti–Nb–Sn alloy. Tuneable nanoscale geometries (unimodal vs. bimodal size distribution with variable length/diameter ratios) can be controllably achieved by varying the anodization conditions, which are highly desirable for enhanced functionalities in widespread applications.
