英文摘要	This work successfully demonstrates metal organic framework (MOF) derived strategy to prepare nanoporous carbon (NPC) with or without Fe3O4/Fe nanoparticles by the optimization of calcination temperature as highly active electrode materials for asymmetric supercapacitors (ASC). The nanostructured Fe3O4/Fe/C hybrid shows high specific capacitance of 600 F/g at a current density of 1 A/g and excellent capacitance retention up to 500 F/g at 8 A/g. Furthermore, hierarchically NPC with high surface area also obtained za from MOF gels displays excellent electrochemical performance of 272 j F/g at 2 mV/s. Considering practical applications, aqueous ASC (aASC) was also assembled, which shows high energy density of. 17.496 Wh/kg at the power density of 388.8 W/kg. The high energy density and excellent capacity retention of the developed materials show great promise for the practical utilization of these energy storage devices.; National Natural Science Foundation of China [51322205, 21371014]; New Star Program of Beijing Committee of Science and Technology [2012004]; SCI(E); EI; PubMed; ARTICLE; rzou@pku.edu.cn; 3; 2148-2157; 8
