One-step fabrication of N-O-P ternary-doped hierarchical porous carbon from kitchen waste for energy storage application

N-O-P ternary-doped carbon materials (NOPCs) with hierarchical porous structure were prepared by a scalable, facile and one-step synthetic approach using kitchen waste as precursor without any extra nitrogen or phosphorus sources. The porous structure, morphology and surface element mapping of NOPCs were fully investigated by N2 adsorption-desorption analysis and TEM coupled with energy dispersive spectrometer. The investigations illustrated...
