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.

Description

technical field

[0001] The invention relates to the technical field of photocatalytic thin film materials, in particular to a method for preparing a photocatalytic thin film based on Mo-doped TaN and its product and application. Background technique

[0002] In the 21st century, ecological and environmental governance issues have become the focus of the world, and environmental problems such as water pollution are getting worse. Therefore, it is particularly important to develop effective sewage treatment technologies. Photocatalytic technology can use photocatalytic materials to absorb solar energy to degrade organic pollutants in water. Therefore, finding efficient, stable, recyclable, pollution-free, simple and low-cost photocatalytic materials has always been the most challenging in solar energy utilization. one of the subjects. In previous studies, in order to increase the contact area between the catalyst and water, most photocatalysts were designed as powder material...
