Easy synthesis of hollow core, bimodal mesoporous shell carbon nanospheres and their application in supercapacitor.
Hollow core, mesoporous shell carbon nanospheres (HCMSs) with large bimodal mesopores (6.4 and 3.1 nm) and high surface area (1704 m(2) g(-1)) have been synthesized by a triconstituent surface co-assembly of monodisperse silica nanospheres method. The resulted HCMS show a high specific capacity of 251 F g(-1) at 50 mV s(-1) in 2 M H(2)SO(4) and long cyclic life.
