金属有机骨架（MOF）复合材料前体的设计和构建最近被认为是制备不同结构的金属/碳基功能材料的有前途的策略。在这里，报道了一种用于合成单孔钴/N掺杂碳中空颗粒的MOF复合辅助策略。首先合成了蛋黄壳聚苯乙烯@沸石咪唑骨架-67（PS@ZIF-67）复合前驱体，然后通过控制热解得到每个壳上具有大的单孔的钴/N掺杂的碳中空颗粒。此外，本工作中报告的MOF涂层方法可以扩展到制备具有不同结构和组成的各种核壳ZIF-67复合材料。得益于结构和组成优势，所衍生的单孔钴/N掺杂碳中空颗粒表现出上级电催化氧还原性能，具有高活性和优异的耐久性。
Design and construction of metal‐organic framework (MOF) composite precursors have recently been considered as a promising strategy for the preparation of different structured metal/carbon‐based functional materials. Here, an MOF composite‐assisted strategy to synthesize single‐holed cobalt/N‐doped carbon hollow particles is reported. The yolk–shell polystyrene@zeolitic imidazolate framework‐67 (PS@ZIF‐67) composite precursors are first synthesized, followed by a controlled pyrolysis to obtain cobalt/N‐doped carbon hollow particles with a large single hole on each shell. Moreover, the MOF‐coating approach reported in this work can be extended to prepare various core‐shell ZIF‐67 composites with different structures and compositions. Benefiting from the structural and compositional advantages, the as‐derived single‐holed cobalt/N‐doped carbon hollow particles manifest superior electrocatalytic oxygen reduction performance with high activity and excellent durability.
