Embodiment 1
[0027] Weigh 8g of activated carbon, add 50ml of 1mol / L dilute nitric acid, cook at 60°C for 3 hours, wash with deionized water until neutral, and dry in an oven at 120°C to obtain acid-treated activated carbon. Weigh 3mL concentrated HCl and add 0.0128gLa 2 o 3 Stir until dissolved, then add 2.1ml of HCl with a concentration of 0.019g / mL to 3mL of hydrochloric acid solution 2 IrCl 6 ·6H 2 O aqueous solution, and then impregnated 1.5 g of the above-mentioned acid-treated coconut shell charcoal. Evaporate the solvent in a water bath at 80°C, dry in an oven at 120°C for 10 hours, and roast at 350°C under nitrogen protection for 4 hours to obtain an acid-treated iridium-based catalyst supported on a carbon carrier.
Embodiment 2
[0029] Weigh 8g of activated carbon, add 50ml of 1mol / L dilute nitric acid, cook at 60°C for 3 hours, wash with deionized water until neutral, and dry in an oven at 120°C to obtain acid-treated activated carbon. Then take 4.5g of the activated carbon from the previous step and react with 50ml of concentrated sulfuric acid at 180°C for 10h, wash with hot deionized water until neutral and free of sulfate ions, and oven-dry at 120°C to obtain sulfonic acid-treated activated carbon. Weigh 4mL concentrated HCl and add 0.0298gLa 2 o 3 Stir until dissolved, then add 4.943ml of HCl with a concentration of 0.019g / mL to 4mL of hydrochloric acid solution 2 IrCl 6 ·6H 2 O aqueous solution, and then impregnated 4 g of the above acid-treated activated carbon. Evaporate the solvent in a water bath at 80°C, dry in an oven at 120°C for 10 hours, and roast at 350°C under nitrogen protection for 4 hours to obtain an acid-treated activated carbon-supported iridium-based catalyst.
Embodiment 3
[0031] Weigh 4g of activated carbon and 50ml of concentrated sulfuric acid to react at 180°C for 10h, wash with deheated deionized water until neutral and free of sulfate ions, and dry in an oven at 120°C to obtain sulfonic acid-treated activated carbon. Weigh 3mL concentrated HCl and add 0.0213gLa 2 o 3 Stir until dissolved, then add 3.467ml of HCl with a concentration of 0.019g / mL to 3mL of hydrochloric acid solution 2 IrCl 6 ·6H 2O aqueous solution, then impregnated 2.5 g of the above acid-treated coconut shell charcoal. Evaporate the solvent in a water bath at 80°C, dry in an oven at 120°C for 10 hours, and roast at 350°C under nitrogen protection for 4 hours to obtain an acid-treated activated carbon-supported iridium-based catalyst
