| 英文摘要 | carbon-supported ir3sn/c and ir/c catalysts were simply prepared with nabh4 as a reducing agent under the protection of ethylene glycol at room temperature. tem and x-ray diffraction (xrd) data showed that the catalysts with small particle size exhibited the typical characteristic of a crystalline ir fcc structure. their electro-catalytic activities in comparison with pt/c and pt3sn/c catalysts also prepared by the nabh4 reduction process were characterized by cyclic voltammetry (cv), linear sweep voltammetry (lsv) and chronoamperometry (ca) techniques. the results indicated that ir-based catalysts showed superior electro-catalytic activity towards ethanol oxidation to pt/c and pt3sn/c catalysts, mainly at low potential region. during single-cell tests at 90 degrees c, better performances of ir-based catalysts as anodes were obtained compared to that of pt/c catalyst. the comparable overall performance of ir3sn/c to pt3sn/c makes it a promising alternative choice of anode catalyst for direct ethanol fuel cells.
