| 摘 要： | 为了开发较高能量密度的超级电容器,我们通过简单的溶剂热反应合成了一种三维的钴基金属有机框架(MOF)化合物(KCo7(OH)3(ip)6(H2O)4]·12H2O,Co?ip;ip=间苯二甲酸根),并考察了其作为超级电容器电极材料的性能。Co?ip电极显示出高比电容、良好的循环稳定性和优良的倍率性能。在1 mol·L^-1 KOH溶液中,电流密度为1 A·g^-1时,其最大比电容为1660 F·g^-1。在电流密度为2 A·g^-1条件下,循环3000次后,其比电容的保持率为82.7%。优异的超级电容性能可归因于Co?ip具有纳米尺寸颗粒和三维的多孔结构。

| Abstract: | In order to develop supercapacitors with higher energy density,a three?dimensional cobalt?based metalorganic framework(MOF)compound(KCo7(OH)3(ip)6(H2O)4]·12H2O,Co?ip;ip=isophthalate)was synthesized by simple solvothermal reaction.Its electrochemical performances as a supercapacitor electrode material were investigated.The Co?ip electrode exhibited high specific capacitance,good cycle stability,and superior rate performance.In 1 mol·L^-1 KOH solution,the maximum specific capacitance was 1660 F·g^-1 at a current density of 1 A·g^-1.At a current density of 2 A·g^-1,the retention of specific capacitance was 82.7%after 3000 cycles.The superior supercapacitive performance is attributed to the three?dimensional porous structure of Co?ip and nano?sized particles. |
