摘要: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 N-2 adsorption-desorption analysis and TEM coupled with energy dispersive spectrometer. The investigations illustrated that the NOPCs featured high contents of nitrogen (11.48 at.%), oxygen (35.18 at.%) and phosphorus (1.94 at.%). The optimal NOPCs electrode can deliver a high specific capacitance of 290 F g(-1) in 6 M KOH electrolyte. The assembled NOPCs asymmetric supercapacitor delivered high energy density of 20.5 Wh kg(-1) at the power density of 477.9 W kg(-1). This study significantly provided a promising pathway for the reuse of kitchen waste.
