In order to fabricate the titanium dioxide (TiO2) nanotubes arrays which were used in the photocatalytic degradation of total volatile organic compounds (TVOC) by anodization, the influence of the electrode gap and anode area on the morphology of the titanium dioxide (TiO2) nanotubes was studied. Titanium dioxide (TiO2) nanotube arrays were prepared by anodization with various electrode gaps and anode areas. Field emission scanning electron microscopy was used to investigate the morphology of the TiO2 nanotubes arrays. The results showed that the morphology of TiO2 nanotubes arrays was influenced by electrode gap and anode area. The appropriate anode area and electrode gap were 5 cm × 2 cm and 20 mm, respectively. Thus, TiO2 nanotube arrays with better morphology (with larger dimension and uniform TiO2 nanotubes) were successfully fabricated by anodic oxidation with 5 cm × 2 cm anode area and 20 mm electrode gap at 30 V.
