Effect of Atomic Ordering on the Activity for Methanol and Formic Acid Oxidation of Pt-Based Electrocatalysts

Recently, the use of intermetallics as catalysts in various chemical transformations, such as hydrogenation/dehydrogenation, oxidation, and steam reforming, as well as electrocatalysts for oxygen reduction, and their advantages over random alloys in the same composition have been reported. Herein, the effect of atomic ordering on the activity for methanol and formic acid oxidation of low-temperature fuel cell platinum-based electrocatalysts is discussed, by comparing ordered and disordered structures with the same Pt/M (in which M is the first and second row transition metal) atomic ratio (3 and 1).
