1. A method of making a metal-N/S-doped carbon electrocatalyst, comprising:
cleaning at least one goat hoof;
sonicating the at least one goat hoof;
calcining the at least one goat hoof at a temperature of 300° C. to produce a carbonaceous precursor;
treating the carbonaceous precursor with a HCl solution;
drying the treated carbonaceous precursor;
adding at least one metal salt to the treated carbonaceous precursor; and
heating the at least one metal salt and the treated carbonaceous precursor to form a metal-N/S-doped carbon electrocatalyst.
