摘要：
Hierarchical N-doped porous carbons (NPCs) with large surface area and controllable N-doping are synthesized by ball milling, followed by pyrolysis.As a Zn–air battery cathode, NPCs have comparable discharge performance to precious metal catalysts and more stability.NPCs also exhibit an excellent specific capacity and cycling stability when used as supercapacitor electrodes.
