Rutile nanotubes by electrochemical anodization

We present a facile method to synthesize rutile titanium dioxide nanotubes (R-TiNT), directly in powder form through rapid breakdown electrochemical anodization by modifying the post anodization processing and annealing temperature. Photocatalytic activity of the R-TiNT was examined by evaluating the degradation of rhodamine B dye in visible light.
