N-Doped carbon spheres with hierarchical micropore-nanosheet networks for high performance supercapacitors.
نویسندگان
چکیده
N-doped carbon spheres with hierarchical micropore-nanosheet networks (HPSCSs) were facilely fabricated by a one-step carbonization and activation process of N containing polymer spheres by KOH. With the synergy effect of the multiple structures, HPSCSs exhibit a very high specific capacitance of 407.9 F g(-1) at 1 mV s(-1) (1.2 times higher than that of porous carbon spheres) and a robust cycling stability for supercapacitors.

متن کاملN-doped porous carbon capsules with tunable porosity for high-performance supercapacitors
A procedure for the fabrication of N-doped hollow carbon spheres with a high rate capability for supercapacitors has been developed. The approach is based on a nanocasting method and the use of a nitrogen-rich compound (pyrrole) as carbon precursor. The carbon particles thus produced combine a large BET surface area (~1500 m g) with a porosity made up of mesopores of ~ 4 nm and a high nitrogen ...

متن کاملHigh performance supercapacitors based on highly conductive nitrogen-doped graphene sheets.
Thermal nitridation of reduced graphene oxide sheets yields highly conductive (∼1000-3000 S m(-1)) N-doped graphene sheets, as a result of the restoration of the graphene network by the formation of C-N bonded groups and N-doping. Even without carbon additives, supercapacitors made of the N-doped graphene electrodes can deliver remarkable energy and power when operated at higher voltages, in th...
