The novel hollowed Ni-Co layered double hydroxide polyhedron (H-(Ni, Co)-LDHP) is synthesized via a template-sacrificing approach using ZIF-67 as template. The morphology, crystallinity, porous texture, and chemical state of H-(Ni, Co)-LDHP are examined. It demonstrates that the H-(Ni, Co)-LDHP not only provides rich redox sites but also promotes the kinetics due to presence of numerous rational channels. As a result, the H-(Ni, Co)-LDHP manifests the desirable lithium ions storage performance when employed as anode. This study paves a new way for preparing hollowed nanostructure toward advanced electrochemical applications.
通过以ZIF-67为模板的模板牺牲法合成了新型中空镍钴层状双氢氧化物多面体（H-(Ni, Co)-LDHP）。对H-(Ni, Co)-LDHP的形貌、结晶度、多孔结构和化学状态进行了研究。结果表明，H-(Ni, Co)-LDHP不仅提供了丰富的氧化还原位点，而且由于存在大量合理的通道而促进了动力学。因此，H-(Ni, Co)-LDHP用作阳极时表现出理想的锂离子存储性能。该研究为制备用于先进电化学应用的中空纳米结构开辟了一条新途径。
