dc.description.abstract | We report on the formation and electrochemical properties of Co3O4/Pt nanocomposite electrodes, which were fabricated by an RF magnetron co-sputtering system, for micro-electrochemical capacitors. High-resolution electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy examinations are performed to characterize the structural and chemical properties of the Co3O4/Pt nanocomposite electrodes. It is shown that the Co3O4/Pt6020 nanocomposite electrodes where RF powers of 60 and 20 W were applied to Co3O4 and Pt targets, respectively, give capacitance of 391.6 F/cm(3) at 100 mV/s along with superb high-rate performance, which is much higher that those of Co3O4 only and other nanocomposite electrodes. The improvement is explained in terms of the formation of Co3O4-Pt combined nanostructures and their good electrical conductivity. (C) 2008 Elsevier B.V. All rights reserved. | - |
