Embodiment 1
[0026] Metallic copper (1.5*1.5 cm) was ultrasonically cleaned in sulfuric acid solution, then deionized water and acetone were used for cleaning and drying to obtain metallic copper a; 228 mg of ammonium persulfate and 1 g of sodium hydroxide were dissolved in 10 mL of water to obtain solution A; metal copper a was placed in solution A for 10 min, and metal copper b was obtained after washing; 10 mg trimesic acid ligand and 100 mg polypyrrolidone were dissolved in 2.5 mL N,N-dimethyl In base formamide, solution B was obtained; metal copper b was mixed with solution B, allowed to stand at room temperature for 15 min, and after cleaning, metal copper with metal organic framework material grown on the surface was obtained (see figure 1 ); then soak it in 20 mL of methanol liquid for 3 times and activate it for 15 h each time to obtain the activated metal-organic framework material-coated metal copper; finally put the above material into the flask to evacuate, and then use a syrin...
