[0035] like figure 1 As shown, the preparation method of the iron-doped cobalt imidazolate nanomaterial provided by the embodiments of the present invention comprises the following steps:
[0036] 1) Fully dissolve ferric nitrate and cobalt nitrate in a certain amount of organic solvent at 70°C, stir and dissolve to obtain solution 1; dissolve the organic ligand in a certain amount of organic solvent, and fully stir to obtain solution 2; Slowly pour one into solution two, add organic acid, and stir thoroughly to obtain a mixed solution.
[0037] 2) The resulting mixed solution is transferred to a stainless steel autoclave, and naturally cooled after being kept warm for a period of time;
[0038] 3) A brown product is obtained after centrifugation, and the brown product is washed with ethanol under ultrasonic treatment, and dried in a vacuum oven to obtain the above-mentioned nanomaterial.

Embodiment 1
[0056] The preparation method of the iron-doped cobalt imidazolate nanomaterial provided by the embodiments of the present invention comprises the following steps:
[0057] Firstly, dissolve 0.066g of ferric nitrate and 0.218g of cobalt nitrate in 15mL of organic solvent, and fully stir to form solution 1. Dissolve 0.98g of organic ligand in 15mL of organic solvent and stir well to form solution 2. Slowly pour solution 1 into solution 2 to form a mixed solution, add 100 μL of organic acid, then stir the mixed solution rapidly at room temperature for 15 min, then transfer the mixture to a stainless steel autoclave, and put the autoclave into Keep it in an oven at 160°C for 12 hours; finally, after the temperature of the autoclave is cooled to room temperature, the mixture is centrifuged and washed to obtain a brown precipitate, which is ultrasonically dispersed and washed several times with absolute ethanol. It was collected by centrifugation and dried in a vacuum dryer for 6h...
Embodiment 2
[0059] The preparation method of the iron-doped cobalt imidazolate nanomaterial provided by the embodiments of the present invention comprises the following steps:
[0060] Firstly, 0.06g of ferric nitrate and 0.174g of cobalt nitrate were dissolved in 15mL of organic solvent, and fully stirred to form solution 1. Dissolve 0.98g of organic ligand in 15mL of organic solvent and stir well to form solution 2. Slowly pour solution 1 into solution 2 to form a mixed solution, add 100 μL of organic acid, then stir the mixed solution rapidly at room temperature for 15 min, then transfer the mixture to a stainless steel autoclave, and put the autoclave into Keep it in an oven at 160°C for 12 hours; finally, after the temperature of the autoclave is cooled to room temperature, the mixture is centrifuged and washed to obtain a brown precipitate, which is ultrasonically dispersed and washed several times with absolute ethanol. It was collected by centrifugation and dried in a vacuum drye...
