Porous TiO₂ film was prepared by sol-gel method using PEG1000 as the template. The functions of applied potential and concentration of Na₂SO₄ to the photoelectrocatalytic degradation of methyl orange on TiO₂ films were investigated. There was no obvious electro-degradation when the applied potential was under 1.5 V without the help of UV light irradiation. Photocatalytic activity of the porous TiO₂ film was higher than the film without addition of PEG. Under low applied potential, the porous structured film can degrade more methyl orange compared with the normal one. However, the degradation activity difference caused by the structure difference was not dominant under high applied potential. After the electrolyte concentration increased to a certain value, the degradation rate reached its maximum value, and then dropped afterwards. After 100 min of reaction, degradation rate on the fdms with PEG addition was 69.82%, while it was 72.73% for the film without PEG addition.
