The purpose of this study is to characterize the photo-catalytic efficiency of TiO₂ nanotube with respect to the distribution of anatase phase which can be changed by the annealing temperature of TiO₂ nanotube. TiO₂ nanotube was fabricated by the anodization method in the 0.5 wt% HF electrolyte. And then the TiO₂ nanotube was annealed at temperatures ranging from 380℃ to 780℃ in dry oxygen ambient for 2 h. For the photo-catalytic water-splitting tests, the photocurrent density was measured as a function of applied potential with a potentiostat using a Ag/AgCl reference, Pt counter electrode, and 1M KOH electrolyte under illumination of UV by a Xe arc lamp of 1 KW. According to the UV photo-catalytic water-splitting tests, the nanotube annealed at 560℃ was found to show the highest photocurrent density. |
