METHOD FOR PREPARING CARBON MATERIAL HAVING SP2 HYBRID STRUCTURE WITH CONTROLLED CONTENT OF PYRIDINIC NITROGEN AND PYRROLIC NITROGEN, AND CARBON MATERIAL PREPARED BY SAME

摘要

The present invention relates to: a method for preparing a carbon material with controlled content of pyridinic nitrogen and pyrrolic nitrogen, comprising the step of bringing a super strong acid into contact with a carbon material having a nitrogen-doped sp2 hybrid structure so as to reduce pyridinic nitrogen and pyrrolic nitrogen while maintaining graphitic nitrogen or quaternary nitrogen present in the carbon material; and a carbon material prepared by same.
