Electro-Assisted Photocatalytic Degradation of Methyl Orange on TiO₂ Film Using NH₄Cl as Electrolyte

Abstract:

Porous and smooth TiO2 film electrodes prepared by sol-gel method were used on methyl orange degradation by an electro-assisted photocatalytic degradation process. The results indicates that methyl orange was barely degraded under the potential alone, availing that potential under 1.8 V had no noticeable effect on removal of the dye. The porous film electrode showed better electro-assisted photocatalytic activity than the smooth film electrode when the potential was above 0.6 V. The porous film showed better activity than the smooth film in nearly all the concentration range except for the highest one. The porous film exhibited better activity than the smooth one.
