| 摘 要： | 以循环伏安法在镍铬铁基体上制备了Pt-Ru微粒电极, 用SEM表征该微粒电极的形貌呈球形, 循环伏安法和计时电流法考察了该电极的电化学性能. 结果表明Pt-Ru微粒电极对甲醇的电氧化显示出催化作用, Ru的加入提高了电极的抗中毒能力. 在相同的实验条件下, Pt-Ru微粒电极对甲醇的催化氧化性能高于纯铂电极, 且该电极制作成本十分低廉、操作简便、对环境无污染, 极大减少了贵金属铂的用量, 可用作燃料电池的电极材料.

| Abstract: | An original Pt-Ru bimetallic microparticle elelctrode was prepared by cyclic voltammetry at nichrome substrate. SEM results revealed that the deposits were composed of spherical granular microparti-cles. Cyclic voltammetry and chronoamperometry were used to characterize its electrochemical behavior. The results indicated that the Pt-Ru microparticle electrode improved the properties of the substrate material and enhanced the catalytic activity for methanol electrooxidation. Under the same conditions, the el... |
