A TiO2 nanostructure transformation: from ordered nanotubes to nanoparticles.


Transformation of TiO2 nanotubes (NTs) to truncated tetragonal bipyramidal shape nanoparticles (NPs) was observed upon thermally annealing titanium dioxide (TiO2) ordered nanotube arrays in fluorine ambient, resulting from the reaction of fluorine ions (F(-)) from the electrolyte residues in long nanotubes grown by anodization in ethylene glycol+NH4F… (More)
