Abstract
⺠MnO2 nanoparticles coated onto recently discovered 2-D graphene nanoplatelets were fabricated. ⺠High-performance electrodes for supercapacitors were produced by using the new hybrid material. ⺠The maximum capacitance and energy density obtained for this nanocomposite were 542 F/g and 75.3 Wh/kg at a scan rate of 0.01 V/s in 2 M KCl. ⺠A synergistic effect between GNPs and MnO2 combine the remarkable electrical conductivity of GNPs with the high pseudocapacitance of the MnO2 nanoparticles.
