As a new super capacitor energy storage device, characterized in recent years because of its high power density and long cycle life caused widespread attention. Metal-organic framework material (of MOFs) are a new type of porous material having a high specific surface area, high porosity, and specific sites more metal structures. This paper reviews the recent application of MOFs supercapacitor, followed by controlling the solvent used in the ZIF-67, synthetic, three different structures of the ZIF-67 material. Observed by scanning electron microscopy (SEM) view in different solvents in the as-synthesized ZIF-67 has a significant difference in particle shape and size. The electrochemical cyclic voltammetry (the CV), constant current charge and discharge, and AC impedance electrochemical techniques to characterize the electrochemical properties found that, when the ZIF-67 material is prepared using different solvents, the obtained material performance is different. Wherein, ZIF-67 has a two-dimensional sheet-like structure of the material, due to its ability to provide large specific surface area and rich active site, the best electrochemical performance.

超级电容器作为一种新型的能量存储设备，近年来由于其高功率密度和长循环寿命的特征而引起了广泛的关注。金属有机骨架材料（MOFs）是一种新型的多孔材料，具有高的比表面积、高孔隙率、特殊的金属位点和多种结构。本文回顾了近年来MOFs在超级电容器中的应用研究，随后通过控制合成ZIF-67所使用的溶剂，合成了ZIF-67材料的三种不同结构。通过扫描电镜（SEM）图观察发现，在不同溶剂中所合成的ZIF-67在粒径形状和尺寸上有显著差异。采用循环伏安法（CV）、恒电流充放电、交流阻抗等电化学测试技术对其电化学性能进行表征发现，当采用不同的溶剂来制备ZIF-67材料时，所获得的材料的电化学性能是不同的。其中，具有二维纳米片状结构的ZIF-67材料，由于其能够提供大的比表面积和丰富的活性位点，其电化学性能最优。

As a new type of energy storage device, supercapacitor has attracted wide attention in recent years due to its high power density and long cycle life. Metal organic framework material (MOFs) is a new type of porous material with high specific surface area, high porosity, special metal sites and various structures. In this paper, the application of MOFs in supercapacitors in recent years is reviewed. Then, three different structures of zif-67 are synthesized by controlling the solvents used in the synthesis of zif-67. It was found by SEM that zif-67 synthesized in different solvents had significant difference in particle size, shape and size. The electrochemical properties of zif-67 were characterized by cyclic voltammetry (CV), constant current charge and discharge, AC impedance and other electrochemical testing techniques. Among them, zif-67 with two-dimensional nano sheet structure has the best electrochemical performance because of its large specific surface area and abundant active sites.<br>
