Embodiment 1

[0032] a) Mix graphite phase carbon nitride and zinc chloride uniformly in a mass ratio of 1:15.

[0033] b) Add a certain amount of water to the mixed material obtained in step 1, so that the solvent water accounts for 25% of the total mass.

[0034] c) Stir the mixture obtained in step 2 at 120°C until it forms a uniform and transparent solution.

[0035] d) Dilute the graphite phase carbon nitride solution prepared in step 3 by adding 10 times the mass of water to regenerate the graphite phase carbon nitride from the solvent system.

[0036] The result of the present invention sees figure 1 .

Embodiment 2

[0038] a) Mix graphitic carbon nitride and stannous chloride uniformly in a mass ratio of 1:30.

[0039] b) Add a certain amount of water to the mixed material obtained in step 1, so that the solvent water accounts for 30% of the total mass.

[0040] c) Stir the mixture obtained in step 2 at 150° C. until it forms a uniform and transparent solution.

[0041] d) Dilute the graphite phase carbon nitride solution prepared in step 3 by adding 20 times the mass of water to regenerate the graphite phase carbon nitride from the solvent system.

Embodiment 3

[0043] a) Mix graphite phase carbon nitride, zinc chloride and tin chloride in a mass ratio of 1:13:2 evenly.

[0044] b) Add a certain amount of water to the mixed material obtained in step 1, so that the solvent water accounts for 25% of the total mass.

[0045] c) Stir the mixture obtained in step 2 at 80° C. until it forms a uniform and transparent solution.

[0046] d) Dilute the graphite phase carbon nitride solution prepared in step 3 by adding 20 times the mass of ethanol to regenerate the graphite phase carbon nitride from the solvent system.

Abstract

The present invention discloses a dissolving system and a dissolving method for dissolving graphite phase carbon nitride. The dissolving system comprises: a chemical reagent comprising at least one ofhalide, nitrate or sulfate of lithium, zinc, aluminum and tin; water used as a solvent; and graphite phase carbon nitride to be dissolved, wherein the dosage of the chemical reagent is 20-80% of themass of the total mixture, the solvent accounts for 20-80% of the mass of the total mixture, and the total mixture is a mixture of the graphite phase carbon nitride, the chemical reagent and the solvent. The system and the method have the advantages of environmental protection and good dissolvability.

Description

technical field [0001] The invention discloses a graphite-phase carbon nitride dissolution system and method, belonging to the technical field of nanometer materials. Background technique [0002] Graphite carbon nitride is a two-dimensional semiconductor material composed of carbon and nitrogen elements with excellent performance and stable physical and chemical properties. Due to its good and suitable semiconductor energy band structure, non-toxic and easy-to-obtain raw materials, and no metals, it has received extensive attention in recent years. It has received extensive attention in photodegradation of organic pollutants, photolysis of water to produce hydrogen, photosynthesis, and luminescent quantum dots. Due to its excellent chemical stability, graphitic carbon nitride is difficult to be dissolved by general solvents. Although existing literature reports the method that utilizes concentrated sulfuric acid or sulfonic acid-based solvent to dissolve carbon nitride, i...
