One-dimensional bunched nanostructures have attracted particular research interest for their applications in energy-relate fields. However, developing a reasonable strategy to realize such unique structure design still remains a great challenge. Herein, we first rationally design and synthesize a distinct one-dimensional bunched Ni–MoO2@Co–CoO–NC composite through an efficient strategy of assembling the metal–organic framework (MOF) and transition metal oxide (TMO), in which the MOF-derived Co–CoO–NC polyhedra are stringed by the Ni–MoO2 nanowires. The synthesis strategy only involves the effective integration of the ZIF-67 polyhedron with NiMoO4·xH2O nanowires via solution growth at room temperature followed by a carbonation treatment under an Ar/H2 atmosphere. Benefiting from the favorable morphological and structural merits as well as the synergistic effects from different components, the bunched Ni–MoO2@Co–CoO–NC composite exhibits a remarkable half-battery performance when evaluated as the anode material for both lithium/sodium-ion batteries. Furthermore, electrode kinetic analyses reveal the capacitive-controlled behaviors within the bunched Ni–MoO2@Co–CoO–NC composite. Besides, a Ni–MoO2@Co–CoO–NC//LiFePO4 full cell is fabricated, which can deliver a high energy density of 329 Wh kg–1. The present study could provide an insight into the construction of TMOs and carbon composites with one-dimensional bunched nanostructures.

工程一维束状Ni-MoO 2 @ Co-CoO-NC复合材料，可增强锂和钠的存储性能
一维束状纳米结构因其在能量相关领域的应用而引起了特别的研究兴趣。然而，制定合理的策略来实现这种独特的结构设计仍然是一个巨大的挑战。在这里，我们首先通过一种有效的金属-有机骨架（MOF）和过渡金属氧化物（TMO）的组装策略，合理设计并合成出独特的一维Ni-MoO 2 @ Co-CoO-NC复合材料。由MOF衍生的Co–CoO–NC多面体被Ni–MoO 2纳米线束缚。合成策略仅涉及ZIF-67多面体与NiMoO 4 · x H 2的有效整合O纳米线通过在室温下溶液生长，然后在Ar / H 2气氛下进行碳化处理而制成。Ni-MoO 2 @ Co-CoO-NC复合材料得益于其良好的形态和结构优点以及不同组分的协同效应，当被评估为锂/钠-锂的负极材料时，具有出色的半电池性能。离子电池。此外，电极动力学分析揭示了在成束的Ni-MoO 2 @ Co-CoO-NC复合材料中的电容控制行为。此外，还制作了Ni-MoO 2 @ Co-CoO-NC // LiFePO 4全电池，可以提供329 Wh kg –1的高能量密度。。本研究可以提供一维TMO和具有一维束状纳米结构的碳复合材料的建设的见解。
