Mesoporous Carbon Materials as Electrodes for Electrochemical Supercapacitors
In this paper, we report the synthesis and characterization of mesoporous carbons, which were obtained using SBA-15 silica as the template material and sucrose as the carbon source. The prepared silica template and mesoporous carbons were characterized by nitrogen adsorption-desorption, low angle X-ray diffraction (XRD) and transmission electron microscopy (TEM). Synthesized carbons were used t...
متن کاملHierarchical mesoporous nickel cobaltite nanoneedle/carbon cloth arrays as superior flexible electrodes for supercapacitors
Hierarchical mesoporous NiCo2O4 nanoneedle arrays on carbon cloth have been fabricated by a simple hydrothermal approach combined with a post-annealing treatment. Such unique array nanoarchitectures exhibit remarkable electrochemical performance with high capacitance and desirable cycle life at high rates. When evaluated as an electrode material for supercapacitors, the NiCo2O4 nanoneedle array...
متن کاملNitrogenated porous carbon electrodes for supercapacitors
Nitrogenated porous carbon materials, made by coating the pore surface with nitrogen functional groups from the pyrolysis of hexamine, were characterized and tested for supercapacitor applications. From X-ray photoelectron spectroscopy, the nitrogen content of the nitrogenated carbon sample was found to be 14 wt%. Electrochemical properties from potentiostatic and galvanostatic measurements, an...

Mesoporous ZnCo2O4 nanoflakes grown on nickel foam as electrodes for high performance supercapacitors.
ZnCo2O4 nanoflakes, as electrodes for supercapacitors, are grown on a cellular nickel foam using a cost-effective hydrothermal procedure. The mesoporous ZnCo2O4 nanoflakes have large electroactive surface areas with strong adhesion to the Ni foam, allowing fast ion and electron transport. The nanoarchitecture electrodes deliver an excellent specific capacitance of 1220 F g(-1) at a current dens...
