Abstract

Abstract: 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.

Key words: Electrocatalysis, Platinum stepped surfaces, Electrooxidation, Formic acid
