| 英文摘要 | a carbon-supported ru85se15 chalcogenide catalyst was synthesized via a microwave-assisted polyol process using rucl3 and na2seo3 as the ru and se precursors. the ru85se15 chalcogenide catalyst was characterized by powder x-ray diffraction (xrd), transmission electron microscopy (tem) and inductively-coupled plasma-atomic emission spectroscopy (icp-aes). the xrd pattern for ru85se15/c clearly exhibited the characteristic reflections of metallic ruthenium. the tem image indicated that the ru85se15 chalcogenide catalyst was well dispersed on the surface of the carbon support with a narrow particle size distribution. rotating disk electrode (rde) and single-cell measurements were carried out to evaluate the electrocatalytic activity of the ru85se15 chalcogenide catalyst. the oxygen reduction reaction (orr) activity of the ru85se15/c catalyst was compared with the commercial pt/c catalyst with the absence/presence of methanol. in the absence of methanol, the ru85se15/c catalyst showed a comparable orr activity with the pt/c catalyst. however, in the presence of methanol, the ru85se15/c catalyst showed a better orr activity than the pt/c catalyst. the performance of the membrane electrode assembly (mea) prepared with ru85se15/c as the cathode catalyst in a single proton exchange membrane fuel cell (pemfc) showed the maximum power density of 400 mw cm(-2) at the current density of 1300 ma cm(-2) (c) 2007 elsevier b.v. all rights reserved. |
