Making efficient non-precious metal catalysts for oxygen reduction reaction (ORR) is very important to bring energy conversion and storage systems into realities. Herein, we design and prepare a highly active catalyst by using cobalt metal-organic frameworks (Co-MOFs) as precursor. In consequence, the obtained 1D [email protected] ([email protected],N-doped carbon nanoprisms) by pyrolysis of Co-MOFs at 700 °C possesses similar ORR activity but superior durability to the commercial 20 wt% Pt/C in 0.1 M KOH solution. The high catalytic performance could be attributed to the special nanostructure composed of cobalt nanoparticles encapsulated in S, N co-doped carbon prisms, which integrate the advantages of 1D nanostructures, encapsulated cobalt nanoparticles and S, N Co-doped carbon materials towards ORR. The present work will provide a new strategy for the development of S, N co-doped carbon-based materials with tunable non-precious metal species for electrocatalysis.

制备用于氧还原反应（ORR）的高效非贵金属催化剂对于使能量转换和存储系统成为现实非常重要。本文中，我们以钴金属-有机骨架（Co-MOFs）为前驱体设计并制备了高活性催化剂。结果，通过在700°C的条件下热解Co-MOF所获得的1D [受电子邮件保护]（[受电子邮件保护]，N掺杂的碳纳米棱镜）具有相似的ORR活性，但优于0.1倍于市售20 wt％Pt / C的耐久性M KOH溶液。较高的催化性能可以归因于由包裹在S，N共掺杂碳棱柱中的钴纳米颗粒组成的特殊纳米结构，该纳米结构整合了一维纳米结构，包裹的钴纳米颗粒和S，N共掺杂碳材料对ORR的优势。
