High-efficiency methanol oxidation electrocatalysts realized by ultrathin PtRuM–O (M = Ni, Fe, Co) nanosheets

Abstract

A general method for controlling the synthesis of a class of ultrathin PtRuM–O (M = Ni, Fe, Co) NSs is reported for the first time. By optimizing the metal ratio, the Pt7RuNi2–O NS catalyst is found to have the highest electrocatalytic activity (mass activity, 3.57 A mgPt−1) for the MOR among PtRuM–O NSs and PtRu–O NSs, which is 10.5 times higher than that of commercial Pt/C (0.34 A mgPt−1). And the Pt7RuNi2–O NSs also have better stability and CO anti-poisoning properties in the prepared materials. In addition, the ultrathin Pt7RuNi2–O NS catalyst also shows the highest performance among reported Pt-based catalysts for the MOR in acidic medium.
