Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
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.
