| Abstract: | Chromium doped titanium dioxide(Cr-TiO2)thin film electrodes prepared by liquid phase deposition were used to degrade methyl orange(MO) under visible light with photoelectrochemical method.The films were characterized by electrochemical methods such as I-t,EIS and Mott-Schottky.It was found that Cr-doped TiO2 showed good photoelectrocatalytic activity and the added content of 0.2% film electrode was the best one.Cr-TiO2 film electrodes were used to degrade MO under visible light illumination.Some factors in... |
