Motivated by this, Zhao et al. prepared the N, O, S -doped pillared porous carbon architectures (AMJ) through the integration of heteroatoms doping method, and architectonics design to achieve rapid electron, and ion transport efficiency under high mass loadings for high-rate supercapacitor applications . The heteroatoms doped pillared porous carbon architectures were prepared from the direct pyrolysis of pappus of metaplexis japonica seed (CMJ), which was activated using KOH under argon atmosphere at 850 ˚C. The series AMJ materials were prepared by changing the weight ratio of KOH and CMJ from 1:4 weight ratio, and were abbreviated as AMJ-1, AMJ-2, AMJ-3, and AMJ-4. The SBET was found to be 1530. .5 m 2 g - for AMJ-1, AMJ-2, AMJ-3, and AMJ-4, respectively. The XPS analysis showed the presence of N, O, and S heteroatoms with at% of 2.5, 10.1, and 0.6 %, respectively. Initially, the electrochemical performances of the CMJ, and AMJ electrodes as supercapacitors were investigated with a mass loading of 1.6 mg cm -2 in a three-electrode system with 6 M KOH electrolyte. Among all the CMJ and AMJ electrodes, the highest specific capacitance of 401.5 F g -1 , was delivered by AMJ-3 at a current density of 1 A g -1 , while the CMJ, AMJ-1, AMJ-2, and AMJ-4 electrodes showed the specific capacitances of 175.8 F g -1 , 298.5 F g -1 , 336.9 F g -1 , and 303.9 F g -1 , respectively. AMJ-3 achieved as high as 274.2 F g -1 even at a high current density of 200 A g -1 , with a capacitive retention rate of 68.3%. As shown in Fig. , EIS analysis confirmed that AMJ-3 had the smallest charge transfer resistance (Rct) value of 19 mΩ, versus AMJ-1 (33 mΩ), AMJ-2 (30 mΩ), and AAMJ-4 (89 mΩ). The observed high specific capacitance of AMJ-3 is attributed to its high SBET of (2041.8 m 2 g -1 ), and smaller Rct value than that of other electrodes, along with the fast frequency response (τ0) of 60 ms, indicating its fast ion transport capability. The GCD analysis of AMJ-3 electrode showed the high specific capacitance of 195. 1 F g -1 (2.34 F cm -2 ) at the density of 1 A g -1 , and 121.0 F g -1 (1. 45 F cm -2 ) with a capacitance retention of 62 % at a high mass load of 12 mg cm -2 . At 20 A g -1 current density, the AMJ-3 exhibited the charge/discharge stability with 1 % degradation after 20000 cycles. Further, to determine the potential of AMJ-3 supercapacitor material, symmetric supercapacitors were assembled using two AMJ-3 electrodes in 6 M KOH electrolyte, which was abbreviated as AMJ-3//AMJ-3-3.2 with mass loading of 3.2 mg cm -2 .
