Metal–organic frameworks (MOFs) are very promising self‐sacrificing templates for the large‐scale fabrication of new functional materials owing to their versatile functionalities and tunable porosities. Most conventional metal oxide electrodes derived from MOFs are limited by the low abundance of incorporated metal elements. This study reports a new strategy for the synthesis of multicomponent active metal oxides by the pyrolysis of polymetallic MOF precursors. A hollow N‐doped carbon‐coated ZnO/ZnCo₂O₄/CuCo₂O₄ nanohybrid is prepared by the thermal annealing of a polymetallic MOF with ammonium bicarbonate as a pore‐forming agent. This is the first report on the rational design and preparation of a hybrid composed of three active metal oxide components originating from MOF precursors. Interestingly, as a lithium‐ion battery anode, the developed electrode delivers a reversible capacity of 1742 mAh g⁻¹ after 500 cycles at a current density of 0.3 mA g⁻¹. Furthermore, the material shows large storage capacities (1009 and 667 mAh g⁻¹), even at high current flow (3 and 10 A g⁻¹). The remarkable high‐rate capability and outstanding long‐life cycling stability of the multidoped metal oxide benefits from the carbon‐coated integrated nanostructure with a hollow interior and the three active metal oxide components.

源自多金属金属有机骨架的N掺杂碳包覆的ZnO / ZnCo2O4 / CuCo2O4的形成：走向高速率和长寿命的锂存储

金属有机框架（MOF）由于具有通用的功能和可调节的孔隙率，因此是用于大规模制造新功能材料的非常有希望的自我牺牲模板。衍生自MOF的大多数常规金属氧化物电极受到所结合的金属元素含量低的限制。这项研究报告了通过多金属MOF前体的热解合成多组分活性金属氧化物的新策略。空心N掺杂碳包覆的ZnO / ZnCo ₂ O ₄ / CuCo ₂ O ₄通过将碳酸氢铵作为成孔剂对多金属MOF进行热退火来制备纳米杂化物。这是有关合理设计和制备由MOF前体衍生的三种活性金属氧化物组分组成的混合物的第一份报告。有趣的是，作为锂离子电池阳极，已开发的电极经过500次循环后，在0.3 mA g ^-1的电流密度下可提供1742 mAh g ^-1的可逆容量。此外，即使在高电流（3和10 A g ^-1）下，该材料也显示出大的存储容量（1009和667 mAh g ^-1））。多掺杂金属氧化物具有出色的高倍率能力和出色的长寿命循环稳定性，这得益于具有空心内部结构和三种活性金属氧化物组分的碳涂层集成纳米结构。
