Enhanced Photoelectrocatalytic Degradation of Azo-Dye Pollutants Using Transparent Titania Nanotube Arrays Glass Electrode

Article Preview

Transparent and highly ordered titania nanotube arrays (TNAs) film electrode was synthesized by anodization from the sputtered titanium (Ti) film on a conductive glass and then applied in the degradation of Acid-orange 7 (AO7) model wastewater. The resulting nanotubes have a length of ~900nm and a pore diameter of ~80nm, resting upon a thin barrier layer. Using 20mg L-1 AO7 solutions as a model system, the removal rate of AO7 by the TNAs glass electrode reaches 95.9% within 180min for the fixed bias potential, higher than 86.2% removal by the TNAs metal electrode under the same treatment conditions.
