a N1s, S2p, B1s and P2p spectra. b Schematic of the atomic structure of CNs(NS) after B-doping, P-doping and P/B co-doping as the substrate. In the schematic, white atoms are carbon atoms, red atoms are O atoms, purple atoms are S atoms, green atoms are N atoms, blue atoms are B atoms, and yellow atoms are P atoms. c Elemental content of the samples. d ID/IG values in the Raman spectra. e Complex permittivity, (f) fitted conductivity of the coaxial ring as well as measured powder resistivity. Powder resistivity data are presented as mean values ± SD (n = 3). g Electrochemical impedance spectra. and (h) Impedance Smith charts of CNs(NS), CNs(NS,B), CNs(NS,P), and CNs(NS,P,B).
