以泡沫镍为生长基底、金属有机骨架材料（MOF）为牺牲模板，采用生长-蚀刻-沉积方法合成了中空纳米墙NiCo-LDH材料，并将其用在超级电容器的正极上。通过XRD、SEM、TEM、XPS和电化学工作站对材料的物相以及电化学性能进行表征和测试。结果表明，NiCo-LDH材料表现出强烈的类电池特性，在1 A/g电流密度下获得的比容量为739.9 C/g，远超于Co-MOF电极的160.3 C/g。MOF衍生的材料展现出优异的储能能力，有望应用在超级电容器的正极中。

Taking nickel foam and metal organic frameworks (MOF) as growth substrate and sacrificial template, respectively, a growth-etching-deposition method is reported to design hollow nano-wall NiCo-LDH materials for supercapacitors.These materials are characterized and analyzed by means of XRD, SEM, TEM and XPS.Electrochemical data are collected by using electrochemical workstation.The results show that the prepared NiCo-LDH material exhibits strong battery characteristics.NiCo-LDH delivers a specific capacity of 739.9 C·g^-1 at a current density of 1 A·g^-1, which is much higher than the160.3 C·g^-1 of Co-MOF.MOF derived materials obtain excellent energy storage capacity.It can be expected to apply in the cathode materials for supercapacitors.
