中文摘要	nitrogen-doped carbon (nc) materials have been proposed as next-generation oxygen reduction reaction (orr) catalysts to significantly improve scalability and reduce costs, but these alternatives usually exhibit low activity and/or gradual deactivation during use. here, we develop new 2d sandwich-like zeolitic imidazolate framework (zif) derived graphene-based nitrogen-doped porous carbon sheets (gnpcss) obtained by in situ growing zif on graphene oxide (go). compared to commercial pt/c catalyst, the gnpcss show comparable onset potential, higher current density, and especially an excellent tolerance to methanol and superior durability in the orr. those properties might be attributed to a synergistic effect between nc and graphene with regard to structure and composition. furthermore, higher open-circuit voltage and power density are obtained in direct methanol fuel cells.
