[0033] Such as figure 1 As shown, the preparation method of the multi-component heterogeneous metal organic framework material provided by the present invention comprises the following steps:
[0034] S101: Using precious metal iridium trichloride / ruthenium trichloride and cobalt nitrate hexahydrate as metal source, anhydrous sodium acetate as ligand, mix uniformly in aqueous solution at room temperature to obtain a brown mixed solution that is the precursor;
[0035] S102: Pour the brown mixture obtained above into an autoclave, add a Ti skeleton and react at 80-150° C. for 12-72 hours to finally obtain a mixture;
[0036] S103: After cooling the reacted autoclave to room temperature, centrifuge the obtained mixture to obtain a black precipitate, and then wash and dry the precipitate to obtain a multi-component heterogeneous metal organic framework material.

[0047] Example 1: Preparation of noble metal iridium-doped multi-component heterogeneous metal-organic framework materials according to the present invention
[0048] First, 0.05-0.10 g of anhydrous sodium acetate was dissolved in 10 mL of aqueous solution. 0.03-0.06 g of cobalt nitrate hexahydrate and 0.01-0.03 g of iridium trichloride were dissolved in 10 mL of aqueous solution. Pour the completely dissolved anhydrous sodium acetate into the metal source and stir well. Then transfer the prepared precursor into the inner lining of the reactor, and then add the monolithic Ti-MOF framework to it and stir it rapidly at room temperature for 5-10min, then transfer the mixture to a stainless steel autoclave, and put the autoclave Put it in an oven at 80-150°C and keep it for 12-72h; after the temperature of the autoclave is cooled to room temperature, centrifuge the product to obtain a black precipitate, which is washed alternately with deionized water and ethanol for 2-5 times ,...
