2026-09-15 Preparation of C₃N₅ Nanosheets via Molten Salt Method, and Preparation Method and Application of C₃N₅@Sv-ZnIn₂S₄ Composite doi:10.57760/sciencedb.iga.01380 en This patent discloses the preparation of C₃N₅ nanosheets via the molten salt method and the preparation method of C₃N₅@Sv−ZnIn₂S₄ composite material, as well as its application in the removal of 2,4-DCP&Cr⁶⁺ combined pollution, aiming to solve the problem of low photocatalytic efficiency of g−C₃N₄. Using potassium-lithium-sodium salt and 3-amino-1,2,4-triazole as raw materials, C₃N₅ nanosheets are prepared by molten salt calcination, and then the sulfur vacancy-modified composite material is obtained through liquid phase reaction and sodium borohydride treatment. This material features a large specific surface area and abundant active sites; the S-scheme heterojunction and sulfur vacancies synergistically improve the separation efficiency of photogenerated carriers, exhibiting an excellent degradation and reduction effect on combined pollutants. Under visible light, it can achieve 98.77% degradation of 2,4-DCP and 100% reduction of Cr⁶⁺ to Cr³⁺ within 40 minutes.
