A PVP-assisted pyrolysis strategy that can simply but efficiently transform zeolitic imidazolate framework-67 (ZIF-67) into a Co-embedded N-enriched meso/microporous carbon material (Co-NC) is reported for the first time. Without further acid treatment, Co-NC can reach an excellent electroactivity and long-term durability toward the oxygen-reduction reaction (ORR) and the oxygen-evolution reaction (OER).

PVP辅助将金属有机框架转变为共嵌入的富氮的中孔/微孔碳材料，作为双功能电催化剂†

首次报道了一种PVP辅助的热解策略，该策略可以简单但有效地将沸石咪唑酸酯骨架67（ZIF-67）转化为共嵌入的N富集的介孔/微孔碳材料（Co-NC）。无需进一步的酸处理，Co-NC就可以实现出色的电活性和对氧还原反应（ORR）和氧释放反应（OER）的长期耐久性。
