Beschreibungen/Notizen

• Herein, the growth of transparent TiO 2 nanotube (NT) layers is investigated by complete self‐organized anodization of a metallic Ti layer on fluorine‐doped tin oxide glass, deposited by electron beam evaporation. An initiation‐free open‐top tube morphology can be obtained for such transparent TiO 2 NTs using an optimized second anodization approach combined with a post‐ultrasonication process. The photoelectrochemical properties of open‐top tubes exhibit notable enhancement, primarily attributed to their rapid electron‐transfer kinetics, with a ≈33% increase in the incident‐photon‐to‐electron conversion efficiency value (at 350 nm wavelength) in comparison to classical (initiation‐covered) NTs with a comparable morphology.
