Methyl orange as a model organic dye is removed from wastewaters by photoelectrocatalytic oxidation on a TiO2 nanotubular array-coated anode in a flowing electrolyte cell. The photocatalytic titanium nanotubes produce hydroxyl radicals able to oxidize the organic molecules. Effects of flow rate and applied potential on the removal efficiency are investigated.
