| 英文摘要 | Bottom-up construction of efficient active sites in transition metal-nitrogen-carbon (M-N-C) catalysts for oxygen reduction reaction (ORR) from single molecular building blocks remains one of the most difficult challenges. Herein, we report a bottom-up approach to produce a highly active Cu-N-4-C catalyst with well-defined Cu-N-4 coordination sites derived from a small molecular copper complex containing Cu-N-4 moieties. The Cu-N-4 moieties were found to be covalently integrated into graphene sheets to create the Cu-N-4 active sites for ORR. Furthermore, the activity was boosted by tuning the structure of active sites. We find that the high ORR activity of the Cu-N-4-C catalyst is related to the Cu-N-4 center linked to edges of the graphene sheets, where the electronic structure of the Cu center has the right symmetry for the degenerate pi* orbital of the O-2 molecule. These findings point out the direction for the synthesis of the M-N-C catalysts at the molecular level. |
