Due to the light-sensitive effect of TiO2, it can be produced by various methods and used as a photoelectrode to remove dye.

TiO2 films produced by the anodizing technique were used as a photoelectrode\u0000for the degradation of MB. The reactor contained 400 mL of 20 mg/L MB solution at\u000020 °C.
