Abstract EN
TiO2 nanotube arrays (TNAs) are fabricated on quartz substrate by anodizing E-beam evaporated Ti films.
E-beam evaporated Ti films are directly anodized at various anodizing voltages ranging from 20 to 45 V and their morphological, wetting, and photocatalytic properties are examined.
The photocatalytic activity of the prepared TNAs is evaluated by the photodecomposition of methylene blue under UV illumination.
The TNAs prepared at an anodizing voltage of 30 V have a high roughness of 30.1 nm and a low water contact angle of 7.5°, resulting in a high photocatalytic performance.
The surface roughness of the TNAs is found to correlate inversely with the water contact angle.
High roughness (i.e., high surface area), which leads to high hydrophilicity, is desirable for effective photocatalytic activity.
