| 摘 要： | 通过一步微波法设计合成了含有 Co 和 Zn 的双金属有机骨架结构, 并在氧气氛围下 500 ${^\circ}$C 煅烧衍生获得由纳米粒子组装的 Co-Zn-O 双金属氧化物微米棒材料. 衍生材料延承了双金属有机骨架前驱体的微米棒形貌和多孔特性, 具有两种不同的金属组分之间的协同储锂作用. Co-Zn-O 双金属氧化物作为锂离子电池负极材料时展现了较高的比容量与循环稳定性, 经过 100 圈的充放电循环后, 比容量保持在 1 137 mA$\cdot$h$\cdot$g-1.

| Abstract: | Co/Zn bimetal organic framework precursor (Co/Zn-MOF-74) has been obtained by using the one-step facile microwave-assisted solvothermal method. By calcining the Co/Zn-MOF-74 at 500 ${^\circ}$C under air, the mesoporous mixed-metallic Co-Zn-O microrod can be obtained. When applied as the anode materials for lithium-ion batteries, the Co-Zn-O electrode exhibits good electrochemical properties (reversible capacity of 1 137 mA$\cdot$h$\cdot$g-1 after 100 cycles), which could be attributed to its mesoporous nanostructure along with the synergistic effects between two different metal species. |
