Problems solved by technology

In previous studies, in order to increase the contact area between the catalyst and the water body, most photocatalysts were designed as powder materials. Although the photocatalytic efficiency was improved, it was greatly affected by process factors, the shape was not easy to control, and it was prone to agglomeration. Poor stability, difficult to recycle and reuse, easy to cause secondary pollution and other problems

Abstract

The invention relates to the technical field of photocatalytic film materials, in particular to a preparation method of a photocatalytic film based on Mo-doped TaN as well as a product and application of the photocatalytic film based on Mo-doped TaN. Specifically, argon serves as sputtering gas, nitrogen serves as reaction gas, the photocatalytic film based on Mo-doped TaN is prepared on the surface of a substrate through a double-target co-sputtering method, and the double targets are a tantalum target and a molybdenum target. The invention provides a preparation method of the photocatalytic film based on Mo-doped TaN. A TaN film is applied to the field of photocatalysis for the first time, and the photocatalytic performance of the TaN film is improved by selecting Mo as a doping agent through a magnetron sputtering vacuum coating technology, so that the light absorption performance of the film and the carrier transport characteristic in the film are improved, and the photocatalytic performance is improved.
