dc.description.abstract | Inhibiting CO formation can more directly address the problem of CO poisoning during methanol electro‐oxidation. In this study, 1D self‐supported porous PtAuP alloy nanotube arrays (ANTAs) are synthesized via a facile electro‐codeposition approach and present enhanced activity and improved resistance to CO poisoning through inhibiting CO formation (non‐CO pathway) during the methanol oxidation reaction in acidic medium. This well‐controlled Pt‐/transition metal‐/nonmetal ternary nanostructure exhibits a specific electroactivity twice as great as that of PtAu alloy nanotube arrays and Pt/C. At the same time, PtAuP ANTAs show a higher ratio of forward peak current density (If) to backward peak current density (Ib) (2.34) than PtAu ANTAs (1.27) and Pt/C (0.78). The prominent If/Ib value of PtAuP ANTAs indicates that most of the intermediate species are electro‐oxidized to carbon dioxide in the forward scan, which highlights the high electroactivity for methanol electro‐oxidation. | - |
