Metal organic frameworks (MOFs) with numerous potential pseudocapacitive sites are quite appealing to supercapacitors with high specific and areal capacitances. However, MOFs suffer from a low conductivity nature, resulting in a mediocre electrochemical performance. Herein, we propose a template-growth strategy of MOF to enhance both specific and areal capacitances of MOF as the electrode material for supercapacitor. As the loading mass of MOF increases from 2 to 5 mg, the specific capacitance also increases from 937 to 2387 Fg-1 (431 to 1098 Cg-1) and areal capacitance 1.87 to 11.94 Fcm-2 (0.86 to 5.49 Ccm-1). Accordingly, a hybrid supercapacitor involving MOF, active carbon as the electrodes can deliver a maximum energy density of 67 Wh kg-1 and a maximum power density of 6000 W kg-1. These results point to a way to fabricate MOF electrode of supercapacitor with high specific and areal capacitance, which leads them to a more practical future.

通过定向调节释放金属有机骨架协同比电容和面电容的潜力

具有许多潜在赝电容位点的金属有机框架 (MOF) 对具有高比电容和面电容的超级电容器非常有吸引力。然而，MOFs 具有低导电性，导致电化学性能平庸。在此，我们提出了 MOF 的模板生长策略，以提高 MOF 作为超级电容器电极材料的比电容和面电容。随着 MOF 的负载质量从 2 mg 增加到 5 mg，比电容也从 937 增加到 2387 Fg-1（431 到 1098 Cg-1），面积电容也从 1.87 增加到 11.94 Fcm-2（0.86 到 5.49 Ccm-1） . 因此，采用 MOF、活性炭作为电极的混合超级电容器可以提供 67 Wh kg-1 的最大能量密度和 6000 W kg-1 的最大功率密度。
