Abstract

A series of organic-phased TiO2 nanotube array electrodes were synthesized with different water content, voltage and time by anodic oxidation of Ti foil in C2H6O2/NH4F/H2O electrolyte. The structure and optical properties of the TiO2 nanotube array electrodes were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Photoelectrochemical techniques. The results show that the TiO2 nanotube array electrode, which was prepared by 2vol% H2O electrolyte and 60V direct current(DC) voltage with an increasing rate of 0.1V•s-1, exhibited a distinguishable orderly array structure and higher quantum efficiency. The as prepared TiO2 nanotube array electrode presented a positive photoelectrocatalytic effect on removing Methylene blue (MB) from the aqueous solution.
