Enhancing the performance of supercapacitor electrodes from corncob-derived 3D hierarchical porous carbon: Effects of N concentration

Enhancing the performance of supercapacitor electrodes from corncob-derived 3D hierarchical porous carbon: Effects of N concentration

We report supercapacitors from hierarchical porous carbon nanostructures (HPCNs) by simple pyrolysis of corncob (CC), with urea doping providing performance comparable to the more common metal-doped electrodes. Via a systematic study of N doping, we establish for the first time that the types of nit...
