Background
With the development of the chemical industry, environmental pollution is increasingly serious. The discharge of printing and dyeing wastewater is one of the important causes of water pollution. There is a large amount of commercial dye emissions each year, and these dyes are chemically stable and cause great harm to the ecological environment. The characteristic that the semiconductor oxide material can be stimulated and activated under the irradiation of sunlight is utilized, so that organic matters can be effectively oxidized and degraded into small molecules such as carbon dioxide, water and the like. Compared with the traditional purification method, the semiconductor photocatalysis technology has the advantages of mild reaction condition, no secondary pollution, simple operation, obvious degradation effect and the like. The common traditional photocatalyst is made of titanium dioxide, zinc oxide and other materials with larger forbidden band width, and has better photocatalytic performance. Of course, these materials have better catalytic performance in the ultraviolet region and have certain limitations in practical life.
Besides the sterilization effect, the silver molybdate material can be used as a novel photocatalysis material, which not only has the sterilization effect on sewage under the illumination condition, but also can treat organic pollutants in the water phase by the photocatalysis technology.
In order to improve the catalytic efficiency of silver molybdate as a photocatalyst, various means have been employed to modify the material. The silver molybdate is loaded through copper and the mesoporous morphology is controlled, so that the spectral absorption range of the silver molybdate is obviously improved, and the effective separation and transmission of photo-generated charges are promoted, so that the photocatalytic performance of the material is improved; meanwhile, the oxygen defect can further improve the photocatalysis performance of the material
