1. A regeneration method of a nitrogen-containing carbon catalyst, comprising:
roasting the nitrogen-containing carbon catalyst in a nitrogen-containing atmosphere to obtain a treated nitrogen-containing carbon catalyst, wherein the nitrogen-containing atmosphere is a mixed gas composed of a first gas and a second gas, the first gas is at least one from the group consisting of ammonia and N2O, the second gas is an inert gas, and a mass fraction of the first gas in the mixed gas is less than or equal to 25%;
then switching the nitrogen-containing atmosphere to an inert atmosphere; and
cooling the treated nitrogen-containing carbon catalyst in the inert atmosphere to obtain a regenerated nitrogen-containing carbon catalyst.
