Embodiment 1
[0032] Put 0.5g of graphite flakes and 10.1g of benzoyl peroxide in benzene solution, heat, stir and reflux in an oil bath at 80°C for 3h, filter, wash with chloroform and ethanol three times, and dry at 60°C. Put 0.5g of phenyl-functionalized graphite flakes into 80mL of 30% oleum (the oleum with a mass content of 30% sulfur trioxide), heat, stir and reflux for 5h, centrifuge, wash with water until the pH value of the solution is close to 7, 60°C Dry to obtain benzenesulfonic acid functionalized graphite flakes. Add 0.15g of graphite flakes functionalized with benzenesulfonic acid, 13mg of cobalt acetate tetrahydrate, and 0.05mL of water into 20mL of ethanol solution, ultrasonicate for 5min, stir at room temperature for 10min, add 0.064mL of 25% concentrated ammonia water dropwise, stir for 10min, and finally Hydrothermal synthesis at 150°C for 2 hours, the product was centrifuged, washed three times with water, and dried at 60°C for 12 hours to obtain nano cobalt oxide suppo...
