| titleOfInvention | Titanium dioxide photocatalytic film with three-layer structure and preparation method thereof |
| abstract | The invention belongs to the technical field of photocatalytic films, and particularly relates to TiO with a three-layer structure 2 A photocatalytic film and a preparation method thereof. In the photocatalytic film of the invention, the bottom layer is TiO doped with Mo 2 The film, the middle layer is methylamine lead-iodine perovskite film, and the top layer is TiO doped with Mo 2 A film; wherein the Mo-doped concentration of the bottom layer and the top layer is the same or different. The invention adopts the vapor deposition technology under the full vacuum environment and utilizes the magnetron sputtering and vacuum evaporation methods to prepare TiO with a three-layer structure 2 A photocatalytic film. The invention introduces methylamine lead-iodine perovskite type narrow band gap material into Mo-doped TiO 2 The film is used as an intermediate layer and can generate a large number of electron-hole pairs under visible light; and a plurality of built-in electric fields which can be modulated are implanted into the film by utilizing the Fermi energy level difference between the multiple layers of film layers and the layers, so that the mobility of carriers is effectively improved. Thus obtaining a multilayer TiO with high efficiency light absorption and photocatalytic activity 2 The film has good practical value. |
