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.
