Facile synthesis of titanium dioxide doped activated carbon fibers for electric double layer capacitor |
| 초록 |
In this study, TiO2 doped activated carbon fibers (ACF) are prepared without heat-treatment as an electric double layer capacitor electrode materials. ACF are treated with different concentration of titanium isopropoxide solutions. These treated ACFs are sintered by ultrasonication at room temperature. The morphology and crystallinity of prepared samples are observed by scanning electron microscope (SEM) and x-ray diffraction (XRD), respectively. Contact angles of the electrodes are also measured from water drop on the electrodes to estimate hydrophilic property of the ones. The specific capacitance of TiO2 doped ACF based electrodes are estimated by cyclic voltammetry (CV). The specific capacitances of TiO2 doped ACF based electrode reached 62 F/g at scan rates of 50 mV/s, which is 93.75% higher than that of pristine ACF based electrode. These results are attributed that TiO2 doped on ACF surface enhances the wettability of electrode and increases ion-transport rate within ACF pores. |
