Embodiment 1
[0018] Weigh 1000g of sucrose, 250g of 6-benzyl adenine, FeCl 3 50g, mixed thoroughly, added to 20ml of concentrated sulfuric acid, oxidized and carbonized at room temperature for 14 days, washed, dried, and ball milled with a ball mill; finally, in a tube furnace, under nitrogen protection, graphitized at 600°C for 2 hours to obtain chlorinated Iron-activated nitrogen-containing purine cathode catalyst.
[0019] Through the oxygen reduction test, it was found that on the nitrogen-containing purine cathode catalyst electrode activated by ferric chloride under acidic conditions, the onset potential and half-wave potential of the oxygen reduction reaction were positively shifted by 487mV and 293mV respectively; The onset potential and half-wave potential of the reaction shifted positively by 220 mV and 56 mV, respectively.
Embodiment 2
[0021] Weigh 1250g of sucrose, 250g of 6-benzyl adenine, FeCl 3 50g, mixed thoroughly, added to 20ml of concentrated sulfuric acid, oxidized and carbonized at room temperature for 14 days, washed, dried, and ball milled with a ball mill; finally, in a tube furnace, under nitrogen protection, graphitized at 700°C for 1 hour to obtain chlorinated Iron-activated nitrogen-containing purine cathode catalyst.
[0022] Through the oxygen reduction test, it was found that on the nitrogen-containing purine cathode catalyst electrode activated by ferric chloride under acidic conditions, the onset potential and half-wave potential of the oxygen reduction reaction were positively shifted by 466mV and 287mV respectively; The onset potential and half-wave potential of the reaction shifted positively by 215 mV and 52 mV, respectively.
Embodiment 3
[0024] Weigh 1000g of sucrose, 250g of 6-benzyl adenine, FeCl 3 50g, mixed thoroughly, added to 20ml of concentrated sulfuric acid, oxidized and carbonized at room temperature for 14 days, washed, dried, and ball milled with a ball mill; finally, in a tube furnace, under nitrogen protection, graphitized at 800°C for 2 hours to obtain chlorinated Iron-activated nitrogen-containing purine cathode catalyst.
[0025] Through the oxygen reduction test, it was found that on the nitrogen-containing purine cathode catalyst electrode activated by ferric chloride under acidic conditions, the onset potential and half-wave potential of the oxygen reduction reaction were positively shifted by 550mV and 388mV respectively; The onset potential and half-wave potential of the reaction shifted positively by 242 mV and 71 mV, respectively.
