Paper Title:
Investigation of TiO2 Nanotube Electrodes: Fabrication, Annealing and Electrochemical Properties
  Abstract

Highly-ordered titania nanotube electrodes were fabricated by electrochemical anodization of pure titanium foil in potassium fluoride electrolyte. The nanotube electrodes were then annealed at different temperatures (300°C,500°C and 600°C) in air for 3 hours. The morphology and crystallinity of nanotube arrays were studied by SEM and XRD. The electrochemical properties of titania nanotube electrodes before and after annealed under different temperatures were investigated by means of cyclic voltammetry with 10mM K3[Fe(CN)6] as an electrolyte at a sweep rate of 0.1V/s.A pair of oxidation/reduction peaks was observed during the test. The results show that the higher annealing temperature, the larger oxidation/reduction peak separation. Photocurrent response was also measured in 0.01M Na2SO4 under the UV-Vis illumination.
