The invention belongs to the technical field of new material preparation, and provides a safe, reliable, simple and feasible method for preparing a TiO 2 MXene photocatalytic composite thin film, including the preparation of Ti 3 C 2 T x MXene thin film by spin coating; Ti 3 C 2 T x The MXene film is dried; the dried Ti 3 C 2 T x MXene film is placed in a resistance furnace, heated in an air atmosphere for different times, and then the film is taken out to obtain TiO 2 ‑Ti 3 C with different TiO 2 contents 2 T x composite film. In the TiO 2 ‑Ti 3 C 2 T x composite thin film prepared by the invention, the Schottky potential barrier formed between Ti 3 C 2 T x and TiO 2 can promote the unidirectional flow of electrons, increase the photocatalytic efficiency, and has a negative effect on cations. The dyes have stronger catalytic performance and good cycle stability, and can be used in fields such as photocatalytic degradation of organic pollutants. |
