%X 本文通过利用基于钴金属有机骨架材料(ZIF-67)的高表面积和良好的结晶度作为前驱体，通过氮气气氛高温煅烧后形成C-ZIF-67材料，并通过原位聚合法，在C-ZIF-67材料表面生长密度均匀的聚苯胺(PANI)化合物，最终获得C-ZIF-67/PANI复合材料。采用CV、GCD和EIS电化学技术研究了C-ZIF-67/PANI复合电极在1 M硫酸电解液中的储能性能。最终表明，C-ZIF-67/PANI5复合电极可提供450.5 F g−1的比电容，并且在电流密度为8 A g−1下经过5000次的充放电循环测试后，比电容值仍保持初始比电容值的71%，表现其良好的循环稳定性。
In this paper, the cobalt metal-organic framework material (ZIF-67) with high surface area and good crystallinity was used as the precursor. The C-ZIF-67 material was formed after calcination at high temperature under N2 atmosphere. Then, through the in-situ polymerization method, the polyaniline (PANI) compound with a uniform density was grown on the surface of the C-ZIF-67 material, and finally the C-ZIF-67/PANI composite material was obtained. The electrochemical techniques such as cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS) were employed to investigate the energy storage performance of the C-ZIF-67/PANI composite electrode in 1 M sulfuric acid electrolyte. Eventually, it was demonstrated that the C-ZIF-67/PANI5 composite electrode could provide a specific capacitance of 450.5 F g⁻¹, and after 5000 charge-discharge cycling tests at a current density of 8 A g⁻¹, the specific capacitance value still remained 71% of the initial specific capacitance value, indicating its good cyclic stability.
