چکیده انگلیسی
Here we introduce a novel approach of preparing TiO2 films on conductive substrates at low temperature by electrophoretic deposition method without successive calcinate treatment. The photocatalytic activity of the non-calcinated TiO2 film was evaluated by degradation rate of methyl orange (MO). We found that the degradation rate of MO increased with the amount of TiO2, and it was higher in both acidic and alkaline media than under neural condition. In addition, lower pH was more favorable for the degradation of MO. The photocatalytic degradation of MO could be described as pseudo-first order reactions. When the initial concentration of MO increased from 1Â mg/L to 10Â mg/L, the highest degradation rate was achieved at 5Â mg/L. The apparent reaction rate constant was calculated to be 0.0098Â minâ1.
