B/P/N/O co-doped hierarchical porous carbon nanofiber self-standing film with high volumetric and gravimetric capacitance performances for aqueous supercapacitors

Effect of pore structure and doping species on charge storage mechanisms in porous carbon-based supercapacitors

“…Although tri-heteroatom doped carbon materials have been relatively less studied in comparison to mono-or dualheteroatom doped carbon materials, tri-heteroatom doping can also lead to in some cases better electrochemical performances. [167][168][169][170] As above reviewed, O and N heteroatoms can effectively induce pseudocapacitance of the carbon surface due to electron-acceptor/electron-donor properties and regulate the hydrophilic properties of carbon. B-doping can modify the electronic structure of carbon, facilitate charge transfer and enhance the electrochemical performance.…”

Metal–Organic‐Framework‐Derived Nanostructures as Multifaceted Electrodes in Metal–Sulfur Batteries

“…As a result, the production has hierarchical porous structures possessing macro‐, meso‐, and micropores and preserves nitrogen moieties. Moreover, of course, heteroatoms, such as (N, P), [ 86 ] (N, P, S), [ 87 ] or (N, P, O, B), [ 88 ] etc., codoped hierarchical porous carbon should also serve as promising structures.…”

One-step production of N–O–P–S co-doped porous carbon from bean worms for supercapacitors with high performance

“…The N, O, S and P elements existing on the surface of carbon material could improve the wettability of samples to electrolytes, which are responsible for the low R s . 21 Remarkably, BWPC 1/3 electrode exhibits smaller R s (0.76 U) and R ct (3.11 U) value than that of BWC (0.87 and 22.01 U), BWPC 1/4 (0.81 and 7.75 U) and BWPC 1/2 (0.84 and 5.46 U) (Table S2 †), suggesting its relatively higher electrolyte ion transport rate and good conductivity.

“…6,19 In comparison to mono-heteroatom doping, multi-heteroatom doping can further enhance the overall performances of the carbon materials because of the synergetic interaction between different heteroatoms. [20][21][22] Therefore, enormous efforts are devoted to optimizing the electrochemical performance of carbon materials by incorporating multiple heteroatoms into the framework of carbon. Nevertheless, to our knowledge, S/P/N/O co-doped carbon has seldom been reported.…”
