Embodiment 1
[0017] 1) 2.91g of Co(NO 3 ) 2 ·6H 2 0. The 2-methylimidazole of 3.28g is dissolved in the anhydrous methanol of 50ml respectively, the two are mixed, vigorously stirred for 10 minutes, then left to stand for 24 hours, the precipitate obtained is collected, washed three times with ethanol, and finally in Vacuum drying at 80°C overnight to obtain MOF;
[0018] 2) Disperse 0.4g of MOF synthesized in 15ml of ethanol, ultrasonically disperse for 10 minutes, and add 1.6g of Ni(NO 3 ) 2 ·6H 2 O was dissolved in 15ml of ethanol, and then added dropwise to the MOF dispersion, then stirred at room temperature for 1 hour, washed by centrifugation with absolute ethanol, dried in a 70-degree oven overnight, and finally heated at 750°C under N 2 Roasting in the atmosphere for 3h;
