Surface oxygen-mediated ultrathin PtRuM (Ni, Fe, and Co) nanowires boosting methanol oxidation reaction
Improving the electrocatalytic activity and durability of electrocatalysts is of vital importance to the direct methanol fuel cells. PtRu materials are the most effective catalysts for methanol oxidation reaction (MOR) in an acidic medium, but they still exhibits partial defects, such as limited cat...

| description | Improving the electrocatalytic activity and durability of electrocatalysts is of vital importance to the direct methanol fuel cells. PtRu materials are the most effective catalysts for methanol oxidation reaction (MOR) in an acidic medium, but they still exhibits partial defects, such as limited catalytic activity. Here, we prepared a series of surface oxygen-mediated ultrathin PtRuM (M = Ni, Fe, and Co) nanowires (NWs) termed PtRuM-O. All these prepared materials showed ultrahigh electrocatalytic activity and excellent durability for MOR in an acidic medium due to their optimal electronic structures induced by the introduction of electroactive O. Until now, in the reported article on Pt-based materials, the optimal Pt
