The 2μm and 650 nm TiO2 nanotube (TNT) arrays were fabricated by sonoelectrochemical anodic oxidation in ethylene glycol (TNT-E) and in aqueous solution (TNT-A) electrolytes at 20 V direct voltage. X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) were used to characterize the crystal phase and surface morphology of the resulting oxide films. UV-Vis diffuse reflectance spectra (UV-Vis DRS), current-time (I-t) curves, Mott-Schottky plots and electrochemical impedance spectroscopy (EIS) were used to investigate their kinetics properties and their electrochemical impedance behavior. The 2 μm nanotubes of TNT-E can help to harvest more light and provide more surface active sites than the 650 nm nanotubes of TNT-A. We found that TNT-E had stronger light absorption than TNT-A after calcination in air at 500 ℃, but the photocurrent density differences between TNT-E and TNT-A was only about 0.05 mA·cm2 under UV illumination ((365±15) nm). Since the longer TNT-E tubes can increase the charge transport resistance and decrease the concentration of the reactants on the electrode surface, TNT-E needs to overcome a larger energy barrier and it has a low charge carrier density of 5.31×1020cm-3. TNT-A with relatively shorter tubes showed a better kinetics property and had a charge carrier density of 9.86×1020 cm-3.
