Nitrogen self-doped porous carbon material derived from metal-organic framework for high-performance super-capacitors

Metal-organic framework materials (MOFs) have extensive application prospects as carbon precursors for super-capacitors are of great interest due to diverse microstructures, uniform pore size, high porosity, and tunable pore parameters. Here, nitrogen self-doped porous carbon materials (ZABC-T) derived from [Zn 2 (BTEC) 0.5 (ATZ) 2 (H 2 O) 3 ]·H 2 O (ZAB) have been prepared via a facile and fast carbonization method at different temperature. The nitrogen self-doped porous carbon material (ZABC-800) features a high specific surface area of 1008 m 2  g −1 and high nitrogen content of 4.09%. Consequently, the ZABC-800 shows an excellent specific capacitance of 316.3 F g −1 at 1.0 A g −1 , superior rate capacity, and remarkable cycling stability (81.9% retention after 5000 cycles). This work indicates that the ZABC-T has a great potential as electrode materials for high performance super-capacitors.
