摘要
超级电容器作为一类优异储能装置具有充放电效率强、使用寿命长和环境友好等诸多优点。近年来,基于金属有机骨架材料前躯体或模板构筑的衍生物逐渐被应用在电化学储能领域。本工作通过采用原位生长法在水滑石(LDH)表面生长ZIF-67构筑了ZIF-67/LDH复合材料,进一步通过硫化处理制备了CoS/LDH衍生物。电化学性能测试表明该衍生物电极材料表现出较高的比电容、优异的比率特性和良好的循环稳定性。该方法为构筑多级结构的电极材料具有重要的借鉴意义。
Supercapacitors have attracted intensive attention as advanced energy storage devices because of their intriguing property. Recently, metal-organic frameworks as precursor generated derivatives are particularly suitable for promising electrodes. Herein, we fabricated Co S/LDH with excellent capacitance performance by in situ growth ZIF-67 on layered double hydroxide followed by sulfurization. The strategy presented here can be extended to explore other electrode materials for potential applications in energy storage fields.
