Nitrogen-doped reduced graphene oxide as electrode material for high rate supercapacitors

Heteroatom-doped graphene as sensing materials: a mini review

“…60,61 Sliwak et al synthesised N-doped GO and employed the material as electrodes for high rate supercapacitors. 62 It was revealed from cyclic voltammetry and impedance spectroscopy measurements that nitrogen doping improved ion diffusion and charge propagation of the material. The rate capacity for N-doped and non-doped GO with increasing scan rate was found to be 98% and 70%, respectively.…”

Germanium quantum dot/nitrogen-doped graphene nanocomposite for high-performance bulk heterojunction solar cells

“…The low doping level of N is attributed to the high reaction temperature which can break some of the C-N bonds. 42,45 Curve tting of the C 1s spectrum (Fig. 5a) mainly yields two peaks at 284.4 and 284.6 eV; these are ascribed to the sp 2 hybridized C, implying that the carbon atoms in the nanocomposite are predominantly packed in a honeycomb lattice structure.…”

Scalable one-pot synthesis of bismuth sulfide nanorods as an electrode active material for energy storage applications

“…Supercapacitors are considered as promising candidates for harvesting and delivering relatively high amount of energy in short periods of time, showing excellent reversibility and long life performance. Besides the carbon materials such as activated carbons, carbon nanofibers, or graphene oxides [1][2][3][4][5][6][7][8], transition metal compounds such as metal oxides or/and hydroxides are considered as attractive potential electrode materials for use in supercapacitors due to the high-capacitance values, which convert into the enhanced energy density [9][10][11]. Transition metal sulfides have been nowadays great candidates for use in hybrid supercapacitors due to their strong faradaic electrochemical response.…”
