A facile one-pot method using molten salt medium is developed to fabricate an open structured N-doped carbon (ONC) derived from biomass. SEM and TEM show the ONC is made up of interconnected thin amorphous carbon layers. N₂ isotherm shows that ONC has hierarchical porous structure with a high specific surface area of 1893.5 m² g^− 1. Compared to commercial Pt/C (20 wt%), the ONC has comparable ORR activity and better durability. Due to its high ORR activity and durability, producing an opened N-doped carbon in this molten salt medium can provide a promising approach for synthesizing heteroatom doped carbons with electrochemical performance.

开发了一种使用熔融盐介质的简便的一锅法，以制备衍生自生物质的开放结构的N掺杂碳（ONC）。SEM和TEM显示ONC由互连的无定形薄碳层组成。N ₂等温线表明，ONC具有分层的多孔结构，其高比表面积为1893.5 m ²  g ^-1。与市售Pt / C（20 wt％）相比，ONC具有可比的ORR活性和更好的耐久性。由于其高的ORR活性和耐久性，在这种熔融盐介质中产生开放的N掺杂碳可以为合成具有电化学性能的杂原子掺杂碳提供一种有前途的方法。
