Abstract

The invention relates to a nitrogen-doped nano-CoS 2 A preparation method and application of graphene photocatalytic materials belong to the technical field of photocatalytic degradation of organic pollutants. In the present invention, after in-situ growth of the ZIF-67 framework on the surface of graphene oxide, high-temperature calcination in the atmosphere of gasified sulfur powder is carried out to carry out metal vulcanization and carbonization of the organic framework, thereby generating highly dispersed nitrogen-doped nano-CoS 2 / Graphene composites. Under visible light irradiation, the composite material obtained by the present invention has a degradation rate of up to 95% for the organic pollutant rhodamine B, which is far superior to that of single nanometer CoS 2 and nitrogen-doped CoS obtained by conventional hydrothermal compounding and subsequent ammonia heat treatment 2 / Graphene photocatalytic material has great application potential.

Description

technical field

[0001] The invention relates to a nitrogen-doped nano-CoS 2 A preparation method and application of graphene photocatalytic materials belong 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 、H 2 In...
