Three-dimensional Zn-MOF-derived nitrogen-doped porous carbon: unlocking high capacitance and long-term stability in supercapacitors

This work reports activated porous N-doped carbon (APNC) using an isonicotinic acid-based Zn-MOF. The APNC exhibits a high specific capacitance of 360 F g −1 at 1 A g −1 , and a symmetric device achieves 18.2 Wh kg −1 at 400 W kg −1 .
