Spiral Growth of One Dimensional Titania Nanostructures Using Anodic Oxidation
One dimensional spiral titania nanostructures were obtained by anodization of pure titanium from fluoride containing solutions of phosphoric acid. The formation of nanotubes was found to be dependant on current density. Field Emission Scanning Electron Microscopy (FESEM)shows the diameter of tubes around 70–100 nm which is consistent with the High Resolution Transmission Electron Micrographs (HRTEM)and Atomic Force Microscopy (AFM)images. HRTEM showed the one dimensional growth as spiral in nature which was also supported by AFM images. This anisotropic growth is compared with the possible growth mechanisms.
