Macroscopic synthesis of ultrafine N–doped carbon nanofibers for superior capacitive energy storage

Porous spherical NiO@NiMoO4@PPy nanoarchitectures as advanced electrochemical pseudocapacitor materials

“…Recently, supercapacitors (SCs) have been regarded as one of hopeful energy storage devices due to the wonderful merits beyond the Li-ion batteries (LIBs), such as super cycle performance, ultrafast charging-discharging and high power density [1][2][3][4][5][6][7][8][9][10]. Compared with transitional electrochemical double layer capacitors (EDLCs) based on carbon-based materials, the pseudocapacitors show larger specific capacitance and bigger energy density.…”

Recent advances in carbon nanostructures prepared from carbon dioxide for high-performance supercapacitors

“…The graphene samples show an elemental composition of 92.8 at % C, 1.5 at% Mg, 4.3 at% O, and 1.4 at% N, exhibiting a low oxygen content and reasonable nitrogen doping. Nitrogen has a similar size as carbon atom and is a good electron-donor, which can enhance the reaction activity and electrical conductivity of electrodes through electron conjugation with carbon framework [112][113][114]. Encouragingly, the amount of Mg-related impurities in the carbon samples is relatively low, probably caused by some Mg or MgO particles adsorbed onto the surface or into the pores of the nanostructure.…”

Assembly of Copolymer and Metal−Organic Framework HKUST-1 to Form Cu2−xS/CNFs Intertwining Network for Efficient Electrocatalytic Hydrogen Evolution

“…In 2012, Chen and coworkers reported 1-D poly (ethylene glycol)-b-poly(4-vinylpyridine) (PEG-b-P4VP) nanowires composed of a PEG shell and slightly crosslinked P4VP core [28] When the aspect ratio of nanowires is high enough, the 3-D intertwining network can be formed. The follow-up research confirmed that the PEG-b-P4VP intertwined nanowires are excellent templates for the nucleation and growth of small MOF crystals due to their high aspect ratio (an average diameter of 30 nm and length up to several microns) and original abundant nucleation sites for metal ions [29] In the electrochemical application, the construction of complex intertwined conductive networks is desired, which would provide fast transport pathways for mass and charge, and then enhance the performance of catalysts [30,31] It is likely that a TMSs/carbon composite intertwining network could be prepared by the vulcanization of the as-prepared PEG-b-P4VP@MOFs network; but this hypothesis remains unexplored.…”
