A novel metal–organic‐framework‐engaged strategy is demonstrated for the preparation of multishelled Co3O4@Co3V2O8 hybrid nanoboxes. This strategy relies on the unique reaction of zeolitic imidazolate framework‐67 with the vanadium source of vanadium oxytriisopropoxide. Benefitting from the synthetic versatility, a series of nanostructures can be realized including triple‐shelled and double‐shelled Co3O4@Co3V2O8 nanoboxes and single‐shelled Co3V2O8 nanoboxes. When evaluated as electrode materials for lithium‐ion batteries, these unique hollow structures demonstrate remarkable lithium storage properties. For example, the triple‐shelled Co3O4@Co3V2O8 nanoboxes retain a high capacity of 948 mAh g−1 after 100 cycles at 100 mA g−1.

具有增强的锂存储特性的金属有机骨架构造复杂的Co3O4 @ Co3V2O8空心结构
演示了一种新颖的金属-有机-框架结合策略，用于制备多壳Co 3 O 4 @Co 3 V 2 O 8杂化纳米盒。此策略依赖于沸石咪唑酸盐骨架67与钒的氧基三异丙氧基钒的独特反应。受益于合成的多功能性，可以实现一系列纳米结构，包括三壳和双壳Co 3 O 4 @Co 3 V 2 O 8纳米盒和单壳Co 3 V 2 O 8纳米盒。当作为锂离子电池的电极材料进行评估时，这些独特的中空结构显示出卓越的锂存储性能。例如，三壳式Co 3 O 4 @Co 3 V 2 O 8纳米盒在100 mA g -1下循环100次后仍保持948 mAh g -1的高容量。
