Y branched TiO2 nanotube arrays synthesized by anodic oxidation

We report a novel synthesis strategy for Y-branched TiO2 nanotubes on a pure titanium foil by electrochemical anodic oxidation in an NH4F organic electrolyte. Effects of temperature range, oxidation time, and morphology-dependent parameters of the Y-branched TiO2 nanotube arrays were investigated. W
