Embodiment 1
[0074] Weigh 5g of activated carbon and put it into a three-necked flask, then add 50mL of 20wt% ammonia water into the flask, stir and impregnate at room temperature for 8h. After impregnation, the filtered activated carbon was put into a tube furnace, heated to 300°C under a nitrogen atmosphere of 20mL / min, and kept at a constant temperature of 300°C for 4 hours to obtain an activated carbon carrier treated with ammonia water. Weigh 0.25g tetrabutylammonium hydroxide (N 4444 OH) and 7.5g deionized water were put into a three-necked flask, mixed and dissolved to make an alkaline ionic liquid solution, and then 0.125g K was added to the ionic liquid solution. 2 PtCl 6 Stir and dissolve evenly to prepare a precursor solution; then add 5 g of the prepared activated carbon carrier treated with ammonia water to the prepared precursor solution, and impregnate at room temperature for 12 hours; after the impregnation is completed, vacuum dry at 80°C for about 8 hours. Put the dried...
Embodiment 2
[0083] Weigh 5g of activated carbon and put it into a three-necked flask, then add 50mL of 20wt% ammonia water into the flask, stir and impregnate at room temperature for 24h. After impregnation, the filtered activated carbon was put into a tube furnace, heated to 300°C under a nitrogen atmosphere of 20mL / min, and kept at a constant temperature of 300°C for 4 hours to obtain an activated carbon carrier treated with ammonia water. Weigh 0.25g tetrabutylammonium hydroxide (N 4444 OH) and 7.5g deionized water were put into a three-necked flask, mixed and dissolved to make an alkaline ionic liquid solution, and then 0.125g K was added to the ionic liquid solution. 2 PtCl 6 Stir and dissolve evenly to prepare a precursor solution; then add 5 g of the prepared activated carbon carrier treated with ammonia water to the prepared precursor solution, and impregnate at room temperature for 12 hours; after the impregnation is completed, vacuum dry at 80°C for about 8 hours. Put the drie...
Embodiment 3
[0085] Weigh 5g of activated carbon and put it into a three-necked flask, then add 50mL of 15wt% ammonia water into the flask, stir and impregnate at room temperature for 8h. After impregnation, the filtered activated carbon was put into a tube furnace, heated to 300°C under a nitrogen atmosphere of 20mL / min, and kept at a constant temperature of 300°C for 4 hours to obtain an activated carbon carrier treated with ammonia water. Weigh 0.25g tetrabutylammonium hydroxide (N 4444 OH) and 7.5g deionized water were put into a three-necked flask, mixed and dissolved to make an alkaline ionic liquid solution, and then 0.125g K was added to the ionic liquid solution. 2 PtCl 6 Stir and dissolve evenly to prepare a precursor solution; then add 5 g of the prepared activated carbon carrier treated with ammonia water to the prepared precursor solution, and impregnate at room temperature for 12 hours; after the impregnation is completed, vacuum dry at 80°C for about 8 hours.
