Examples
Embodiment 1
[0021] Put 1.5 g of activated carbon in 12 ml of 2N nitric acid and stir at 80°C for 1 hour, add 2.0 ml of platinum-containing 0.0148 g / ml solution, continue stirring for 2 hours, cool down to 40°C, add 20 µl of hydroxyethanethiol, continue Stir for 10 minutes, add 1.5 ml of 36% formaldehyde solution, stir for 0.5 hours, add dropwise 4 g equivalent / liter of sodium hydroxide aqueous solution, adjust the pH value of the solution to 8-9, and raise the temperature to 80 ° C to promote the reduction reaction. Add sodium hydroxide solution to keep the pH value in the range of 8-9 until complete reduction. The platinum / carbon catalyst was filtered out, washed with deionized water to remove chloride ions, and dried at 80° C. for 6 hours to obtain a platinum / carbon catalyst containing 2w% platinum and a sulfur / platinum atomic ratio of 1:10.
Embodiment 2
[0023] Put 1.5 g of activated carbon in 12 ml of 2N nitric acid and stir at 80°C for 1 hour, add 2.0 ml of platinum-containing 0.0148 g / ml solution, continue stirring for 2 hours, cool down to 40°C, add 1 ml of hydroxyethanethiol, and continue stirring After 10 minutes, add 1.5 ml of 36% formaldehyde solution, stir for 0.5 hours, add dropwise 4 g equivalent / liter of sodium hydroxide aqueous solution, adjust the pH value of the solution to 8-9, and raise the temperature to 80 ° C to promote the reduction reaction. Add sodium hydroxide solution to keep the pH value in the range of 8-9 until complete reduction. The platinum / carbon catalyst was filtered out, washed with deionized water to remove chloride ions, and dried at 80° C. for 6 hours to obtain a platinum / carbon catalyst containing 2w% platinum and a sulfur / platinum atomic ratio of about 1:5.3.
Embodiment 3
[0025] Put 1.5 g of activated carbon in 12 ml of 2N nitric acid and stir at 80°C for 1 hour, add 2.0 ml of platinum-containing 0.0148 g / ml solution, continue stirring for 2 hours, cool down to 40°C, add 100 µl of hydroxyethanethiol aqueous solution, Continue to stir for 10 minutes, add 1.5 milliliters of 36% formaldehyde solution, stir for 0.5 hours, add dropwise 4 g equivalent / liter of sodium hydroxide aqueous solution, adjust the pH value of the solution to 8-9, and heat up to 80 ° C to promote the reduction reaction. Add sodium hydroxide solution from time to time to keep the pH value in the range of 8-9 until complete reduction. The platinum / carbon catalyst was filtered out, washed with deionized water to remove chloride ions, and dried at 80° C. for 6 hours to obtain a platinum / carbon catalyst containing 2w% platinum and a sulfur / platinum atomic ratio of about 1:2.1.
