Embodiment 1
[0047] Pour 50 milliliters of deionized aqueous solution (molar concentration 0.1 mol / liter) that has dissolved 1.067 grams of palladium chloride dihydrate into 2.5 grams of multilayer graphene, stir and pour into a hydrothermal kettle, and the hydrothermal kettle is ultrasonically oscillated for 1 hour Place in a hydrothermal furnace, keep at 160°C for 24 hours, cool to room temperature, wash with deionized water, pour into a 250ml three-necked flask, add 80.6g of p-chloromethylstyrene, 3.5g of divinylbenzene and 0.1 g of benzoyl peroxide initiator was stirred at 60° C. for 2 hours for prepolymerization. 150 mL of deionized water in which 1.5 g of polyvinyl alcohol had been dissolved was added. Adjust the stirring speed, and at the same time gradually raise the temperature to 80°C, and react for 5 hours; then raise the temperature to 90°C, react for 5 hours, and finally raise the temperature to 98°C, and react for 6 hours. After the reaction, pour out the upper liquid, wash ...
Embodiment 2
[0051] Get 0.585 grams of ammonium metavanadate and prepare 50 milliliters of deionized aqueous solution (molar concentration 0.1 mol / liter), impregnate in 2.5 grams of multilayer graphene powder, stir and pour into a hydrothermal kettle, ultrasonically vibrate for 1 hour, and place in a hydrothermal furnace Keep at 160°C for 24 hours, cool to room temperature, and wash with deionized water to obtain a nano-chromium oxide-graphene composite sample. In a 250 ml three-neck flask, add 80.6 g of p-chloromethylstyrene, 3.5 g of divinylbenzene and 0.1 g of benzoyl peroxide initiator, and stir at 60° C. for 2 hours for prepolymerization. 150 mL of deionized water in which 1.5 g of polyvinyl alcohol had been dissolved was added. Adjust the stirring speed, and at the same time gradually raise the temperature to 80°C, and react for 5 hours; then raise the temperature to 90°C, react for 5 hours, and finally raise the temperature to 98°C, and react for 6 hours. After the reaction, pour o...
