Anodization is a simple and effective method to synthesize self-organized titanium dioxide nanotubes. But depending on the electrolyte used for anodization, there is a disorder “nano grass” or an “initiation layer” on top of the nano tubes. Additionally peeling off the nanotubes from substrate might happen during the anodization of titanium which is sputtered on the fluorine doped tin oxide (FTO). Removing this unwanted layer (without delamination), especially in high length TiO2 nanotubes could increase the photo electrochemical performance. Here we report a novel method to anodize the titanium layer homogenously and to produce open top nano tubes. Results show that the photo current density of samples will be increase up to 15% after opening the top surface of nanotubes.2 nano tubes, anodization, nano grass, initiation layer, sputtering
