Ti3C2Tx MXene embedded metal–organic framework-based porous electrospun carbon nanofibers as a freestanding electrode for supercapacitors

“…57 Pyridinic and oxidic nitrogen have been reported to help increase the conductivity of the carbon network. 58 Similarly, the F 1s transition is deconvoluted into two peaks at 685.1 eV and 686.0 eV assigned to C-Ti-F and O-F, respectively. 34,38 The atomic% of C, Ti, O, F, and N of MX-5@PCNF is 67.72, 4.37, 12.62, 0.08, and 15.21, respectively.…”

Progress in the use of organic potassium salts for the synthesis of porous carbon nanomaterials: microstructure engineering for advanced supercapacitors

“…[11][12][13] PCNs can be obtained by the pyrolysis of various carbon precursors with templates and/or activation agents. [14][15][16][17][18][19][20][21][22][23] PCNs prepared by a template-assisted process usually exhibit a meso-/macro-pore dominated architecture with a relatively low SSA (<500 m 2 g −1 ) and small C sp (<200 F g −1 ), [24][25][26] while PCNs prepared by an activation agent based synthesis usually exhibit micropore-dominated porosity with quite a high SSA (>1000 m 2 g −1 ) and much larger C sp (>300 F g −1 ). 16,27,28 Therefore, activation is considered to be an effective approach for enhancing the capacitance performance of PCNs, and various activation agents have been explored.…”

N, S Codoping and Mesoporous‐Induced Capacitive Storage Enhancement in Supercapacitor and Improved Li–S Battery Performances of Polystyrene Waste‐Derived Carbon Electrode

“…[6] Nitrogen doping results in enhanced conductivity, while sulfur doping imposes strain effect, alters electron density due to the larger size of the sulfur atom, and results in C─S bond polarization. [6] Arti et al synthesized hierarchical porous codoped carbon using ginger as the biomass precursor and reported good storage features in supercapacitors. [7] In addition, to meet the energy demands of the EVs and grid storage, the energy density of the current LIBs needs to be upgraded, as the energy density achieved in the current LIB is limited to 150-300 Wh kg À1 .…”
