Photoelectrochemical Performance of Smooth TiO2 Nanotube Arrays: Effect of Anodization Temperature and Cleaning Methods
Figure 7
FESEM images of TiO2 nanotubes obtained via different cleaning methods after the anodization process; (a) ultrasonically cleaned in distilled water for 1 min and subsequently dried under flowing N2 gas and (b) cleaned by hot rinsing at 90°C using distilled water for 1 min and subsequently dried under flowing N2 gas.
