【摘要】 <正>由于甲醇的来源丰富、价格便宜、容易储存、能量效率高等特点,使得直接甲醇燃料电池(DMFC)成为近年来备受关注的研究课题。虽然人们致力于DMFC的研究和改进,但由于电池阳极氧化的中间产物一氧化碳易使电极材料中毒,导致催化剂的活性降低,而且制备电极耗用大量的贵金属使其成更多还原

【Abstract】 A 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 microparticles. 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. The cost for preparing the electrode was very low by decreasing the amount of noble metal. The Pt-Ru microparticle electrode showed an improved performance towards methanol oxidation.更多还原
