Abstract

The invention relates to a preparation method and application of a nitrogen-doped nanometer ZnS / graphene photocatalytic material, and belongs to the technical field of photocatalytic degradation of organic pollutants. In the present invention, after the in-situ growth of ZIF-8 framework on the surface of graphene oxide, high-temperature calcination in the gasified sulfur powder atmosphere carries out metal vulcanization and organic framework carbonization, thereby generating highly dispersed nitrogen-doped nano-ZnS / graphene composite material . Under the irradiation of visible light, the composite material obtained in the present invention has a degradation rate of up to 97% for the organic pollutant Rhodamine B, which is far superior to single nano-ZnS and nitrogen-doped ZnS / Graphene photocatalytic material has great application potential.

Description

technical field

[0001] The invention relates to a preparation method and application of a nitrogen-doped nanometer ZnS / graphene photocatalytic material, and belongs to the technical field of photocatalytic degradation of organic pollutants. Background technique

[0002] As the problem of environmental pollution becomes more and more prominent, searching for a new, non-polluting and economical solution to environmental pollution has far-reaching significance for the sustainable development of society. Photocatalytic technology is more and more favored by many scientific researchers and companies due to its advantages of energy saving, environmental protection, and efficient degradation of environmental pollutants. Photocatalysts have strong oxidizing ability, which uses solar energy as an effective light source to excite photocatalysts for catalytic reactions, and can quickly (several hours) completely mineralize and degrade organic pollution into CO at room temperature. 2 、...
