For high performance supercapacitor, deposition of Fe3O4 on oxidezed acitivated carbon using hydrazine reducing method |
| 초록 |
Oxidized activated carbon/Fe3O4 (AC/Fe3O4) composites for supercapacitor electrodes were synthesized by a reduction method. Poly(vinylpyrrolidone) was added as a dispersing agent for homogeneous deposition of Fe3O4 on AC. By using N2 adsorption/desorption isotherm analysis, we confirmed that surface areas and pore volumes decreased with increasing Fe3O4 content. We also carried out electrochemical characterization of AC and AC/Fe3O4 composites. Remarkably, we found that the value of specific capacitance increased significantly from 99.4 F g−1 of raw AC to 202.6 F g−1 of AC/Fe3O4 composites at 10 mV s−1 of scan rate. This result can be ascribed to a synergistic effect of the combination of electrical double-layer capacitance and pseudo-capacitance properties. This research represents a valuable contribution to the application of supercapacitor electrodes in regard to cost effectiveness and simple fabrication. |
