▎ 摘  要

NOVELTY - Graphene-type carbon material containing nitrogen-doped carbon five-membered ring structure, is claimed. The carbon material contains carbon five-membered ring structure connected with graphite type nitrogen atom. USE - The graphene-type carbon material containing a nitrogen-doped carbon five-membered ring structure is useful as electrocatalytic oxygen reduction catalyst in acid electrolyte (claimed). ADVANTAGE - The material has high catalytic activity and high stability, and does not contain noble metal. The cost is low. The experiment result shows that the catalytic activity and commercial platinum/carbon are close. The catalytic activity is not obviously reduced after 10000 times of continuous circulation. The current retention rate is higher than the commercial platinum/carbon electro-catalyst after 100 hours of constant voltage reaction; has very good electrochemical oxygen reduction and practical prospect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a preparation method of graphene-type carbon material electro-catalyst containing nitrogen-doped carbon five-membered ring structure; and (2) a method for electrochemical oxygen reduction.
