文摘

Titania nanotubes with 5–20 μm length synthesized under galvanostatic anodization. Close to 50% photocatalytic degradation of caffeine and salicylic acid was attained. 10 μm nanotubes length was optimum for photocatalysis. Small dependence of photocatalytic efficiency on solutions pH attained. TNT films give reproducible activity after 10 photocatalytic cycles.
