Abstract

TiO2 nanotube arrays photoelectrodes were fabricated by anodic oxidation on a pure titanium sheet. The morphology and structure of the nanotube arrays were characterized by SEM and XRD. Oxidation parameters for preparation were investigated. The photoelectrochemical properties of the TiO2 nanotube arrays electrodes were evaluated by steady-state photocurrent response. The results show that the vertical oriented TiO2 nanotube arrays can be obtained at 20V for 30min in 1wt% HF solution. And the aperture size of nanotubes is about 90nm and the thickness of tube wall is about 10nm. The structure of nanotube arrays is a mixture of anatase and rutile through annealed at 600℃. The results of photoelectric testing show that photoelectrochemical properties of TiO2 nanotube arrays electrode annealed at 600℃ are optimum. Compared with TiO2 nanoporous films, the properties of the TiO2 nanotube arrays are enhanced remarkably.
