Embodiment 1
[0026] Mix 5g of cetyltrimethylammonium bromide and 50ml of 1mol / L hydrochloric acid solution in an ice-water bath and stir evenly, then add 5g of potassium persulfate and continue to stir evenly, and finally add 8ml of pyrrole slowly, at 0°C and 1000rpm The mixture was stirred and reacted for 10 hours, and after the reaction was completed, it was washed with absolute ethanol to neutrality to obtain a polymer precursor;
[0027] Dissolve 0.8g of ferric nitrate and 0.5g of cerium nitrate in 50ml of deionized water to prepare a metal salt solution, then add 2.4g of the polymer precursor prepared above, stir at 80°C to remove the solvent, and place the obtained solid in a muffle In the furnace, under an argon atmosphere, first raise the temperature to 500°C at a rate of 1°C / min, and then heat up to 600°C at a rate of 5°C / min for 1 hour, and finally heat up at a rate of 5°C / min. To 800°C, constant temperature treatment for 2h, the carbonized solid was etched with 0.5mol / L sulfuric...
Embodiment 2
[0030] Mix 6g of cetyltrimethylammonium bromide and 60ml of 1mol / L hydrochloric acid solution in an ice-water bath and stir evenly, then add 6g of potassium persulfate and continue to stir evenly, and finally add 10ml of pyrrole slowly, at 5°C and 2000rpm The mixture was stirred and reacted for 20 hours, and after the reaction was completed, it was washed with absolute ethanol to neutrality to obtain a polymer precursor;
[0031] Dissolve 0.8g of ferric nitrate and 0.75g of cerium nitrate in 50ml of deionized water to prepare a metal salt solution, then add 2.4g of the polymer precursor prepared above, stir at 90°C to remove the solvent, and place the obtained solid in a muffle In the furnace, under an argon atmosphere, first raise the temperature to 500°C at a rate of 1°C / min, and then heat up to 600°C at a rate of 5°C / min for 1 hour, and finally heat up at a rate of 5°C / min. To 800°C, constant temperature treatment for 3 hours, the carbonized solid was etched with 0.5mol / L s...
Embodiment 3
[0034] Mix 5.5g of cetyltrimethylammonium bromide and 60ml of 1mol / L hydrochloric acid solution in an ice-water bath and stir evenly, then add 6g of potassium persulfate and continue to stir evenly, and finally add 10ml of pyrrole slowly, at 0°C and 1500rpm Under the condition of stirring and reacting for 15 hours, after the reaction is completed, it is washed to neutral with absolute ethanol to obtain a polymer precursor;
[0035] Dissolve 0.8g of ferric nitrate and 0.55g of cerium nitrate in 50ml of deionized water to prepare a metal salt solution, then add 2.4g of the polymer precursor prepared above, stir at 90°C to remove the solvent, and place the obtained solid in a muffle In the furnace, under an argon atmosphere, first raise the temperature to 500°C at a rate of 1°C / min, and then heat up to 600°C at a rate of 5°C / min for 1 hour, and finally heat up at a rate of 5°C / min. To 800°C, constant temperature treatment for 3 hours, the carbonized solid was etched with 0.5mol / L...
