摘要
通过比较甲酸在Pt(210)、Pt(310)、Pt(610)3个阶梯晶面和在Pt(110)、Pt(100)2个基础晶面上的电氧化特性,揭示了在甲酸氧化中阶梯晶面的电催化特性不仅与该面原子排列对称结构种类有关,还依赖于这些对称结构的有序范围及所处的环境。
By comparing the electrooxidation character of formic acid at Pt(210), Pt(310) and Pt(610) with those at Pt(110) and Pt(100), it is found that the electrocatalytic properties for a stepped surface depend not only on the symmetry of the surface sites contained in this surface, but also strongly on the size of the ordered domain of sites with a given symmetry and the surroundings associated.
