초록
Recently, TiO_2 nanotubes have considerably researched because of their novel application about photocatalysis, dye-sensitized solar cells (DSSCs), lithium ion battery, etc. In this work, self-standing TiO_2 nanotube arrays were fabricated by anodic oxidation method using pure Ti foil as a working electrode in ethylene glycole with 0.3M NH_4F + 2%H_2O. Growth behavior of TiO_2 nanotube arrays was compared according to temperature, voltage and time. The morphology, structure and crystalline of anodized TiO_2 nanotube arrays were observed by FE-SEM (field emission scanning electron microscope) and XRD (X-ray diffraction).
