摘　　要：MOF材料由于其超高比表面积、多样的结构等特点成为高比电容储能材料的研究热点。本文采用快速氧化还原法,以ZIF-67为碳源制备C/MnO_(2)复合材料。通过SEM分析可知复合材料仍然保持ZIF-67的多面体结构,电化学性能分析可知,在KOH电解液中,电流密度为0.5 A/g下比电容为156.5 F/g,10A/g下比电容为72.5 F/g,比电容保持率为54%,具有良好的倍率特性,是一种优良的超级电容器电极材料。MOF materials have become a research hotspot in high specific capacitance energy storage materials due to their ultra-high surface area and diverse structures.This article uses rapid oxidation-reduction method to prepare C/MnO_(2) composite materials with ZIF-67 as the carbon source.According to SEM analysis,the composite material still maintains the polyhedral structure of ZIF-67.Electrochemical performance analysis shows that in KOH electrolyte,the specific capacitance is 156.5 F/g at a current density of 0.5 A/g and 72.5 F/g at 10 A/g,with a specific capacitance retention rate of 54%.It has good rate characteristics and is an excellent electrode material for supercapacitors.
