Hierarchical metal-organic framework derived nitrogen-doped porous carbon by controllable synthesis for high performance supercapacitors

The N-doped porous carbon (HPNCs) are prepared via facile carbonization of zeolitic imidazolate frameworks (ZIF-8) by controllable synthesis and appropriate temperature which have shown outstanding electrochemical behaviors. Such outstanding electrochemical behaviors show the HPNCs-C8//HPNCs-C8 symmetric supercapacitor is a promising practical energy-storage facility.111
