- 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).

Abstract

- Self-standing TiO_2 nanotube arrays were fabricated by potentiostatic anodic oxidation method using pure Ti foil as a working electrode and ethylene glycol solution as electrolytes with small addition of NH_4F and H_2O. The influences of anodization temperature and time on the morphology and formation of TiO_2 nanotube arrays were investigated. The fabricated TiO_2 nanotube arrays were applied as a photoelectrode to dye-sensitized solar cells. Regardless of anodizing temperature and time, the average diameter and wall thickness of TiO_2 nanotube show a similar value, whereas the thickness show a different trend with reaction temperature. The thickness of TiO_2 nanotube arrays anodized at 20°C and 30°C was time-dependent, but on the other hand its at 10°C are independent of anodization time. The conversion efficiency is low, which is due to a morphology breaking of the TiO_2 nanotube arrays in manufacturing process of photoelectrode.
