dc.description.abstract | Endothelium corneum gigeriae galli derived 3D hierarchical nitrogen-doped porous carbon was for the first time prepared by preliminary carbonization at 450 degrees C and final KOH activation at high temperatures. The surface and structural properties of the as-synthesized samples are analyzed with Brunauer-Emmett-Teller surface analyzer apparatus, X-Ray Diffractometer, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectrometer. The electrochemical performances are analyzed by cyclic voltammetry, galvanostatic charge/discharge cycling and electrochemical impedance spectroscopy. The obtained results show that the sample carbonized at 900 degrees C possesses the SSA of 2149.9 m(2) g(-1), average micropore diameter of 1.78 nm, and exhibits the highest initial specific capacitance of 198.0 F g(-1) at current density of 1 A g(-1) in 6 M KOH solution. It retains good specific capacitance retention of 91.6% after 3000 charge/discharge cycles at current density of 2 A g(-1). (C) 2014 Elsevier Ltd. All rights reserved. | en_US |
