| Abstract | The thin films of TiO(2), doped by Mn with different doping modes, were prepared by sol-gel method under process control. The structure of the films was characterized by XPS and SEM. The thin films were evaluated by UV-Vis spectrophotometer and electrochemical workstation. And the activity of the photocatalyst was evaluated by photocatalytic degradation of aqueous methyl orange under UV radiation. The results show that the photocatalytic activity of TiO(2), thin film can be evidently enhanced by MT doping mode with the optimal dopant mass fraction of 0.80%, on the contrary, decreased by MM doping mode. The characteristic of capacitance-tension characteristic of p-n junction in the film was proved by electrochemical characterization. A mechanism for enhanced photocatalytic activity of titanium dioxide film doped by MT mode was discussed in terms of semiconductor p-n junction theory. |
