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

Abstract:

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.
