Embodiment 1
[0029] Step 1): Cut a piece of carbon paper of 0.5x0.7cm, wash it with deionized water, then immerse it in the mixture of concentrated sulfuric acid and concentrated nitric acid (concentrated sulfuric acid 40ml, concentrated nitric acid 20ml) for 30min, then put 6g permanganate Add potassium to the mixture and stir at room temperature for 1 hour, then slowly add deionized water to 100ml under ice bath, and stir for 2 hours, finally add hydrogen peroxide dropwise until the solution becomes clear, take out the carbon paper and wash it with deionized water , and vacuum dried for 12 hours.
[0030] Step 2): Weigh 0.01g (0.075mmol) of 2-amino-5-mercapto-1,3,4-thiadiazole, add 0.8ml of concentrated sulfuric acid (96-97wt%) to 150ml of deionized water, and sonicate for 15min to All dissolved, and then transferred to the electrolytic cell for electropolymerization, 100 cycles of polymerization, scanning speed 50mv / s, voltage range -0.2V-1.7V. The obtained product was washed with deio...
