Embodiment 1
[0026] In this example, a preparation method of a composite organic framework nano electrode material is synthesized by a one-pot microwave stirring method, and a composite organic framework nanometer electrode material is obtained through the interconnection hybridization of a covalent organic framework and a metal organic framework based on Mn-N bonds. materials, including the following steps:
[0027] a. Weigh 16mg of 1,3,5-benzenetricarbaldehyde and 16mg of 1,4-diaminobenzene, ultrasonically disperse them in 1mL of 1,4-dioxane, and then make the molar concentration of 0.2mL Add 3M acetic acid aqueous solution to the suspension, and after further stirring for 5 hours at room temperature of 25°C, a yellow solid precipitate is obtained. Use N,N-dimethylformamide and tetrahydrofuran as solvents, and centrifuge the obtained precipitate , using THF as a solvent, Soxhlet extraction, and drying at 60°C for 12 hours, the yellow covalent organic framework material was collected;

Embodiment 2
[0038] This embodiment is basically the same as Embodiment 1, and the special feature is that the following synthetic processes are different:
[0039] In this example, a preparation method of a composite organic framework nano electrode material is synthesized by a one-pot microwave stirring method, and a composite organic framework nanometer electrode material is obtained through the interconnection hybridization of a covalent organic framework and a metal organic framework based on Mn-N bonds. materials, including the following steps:
[0040] a. Weigh 16 mg of 1,3,5-benzenetricarbaldehyde and 10.7 mg of 1,4-diaminobenzene, and ultrasonically disperse them in 2 mL of 1,4-dioxane. Aqueous acetic acid solution with a concentration of 3M was added to the suspension, and after further stirring at room temperature of 30°C for 6 hours, a yellow solid precipitate was obtained. Using N,N-dimethylformamide and tetrahydrofuran as solvents, the obtained precipitate was centrifuged Pr...
