TePbPt Alloy Nanotube as Electrocatalyst with Enhanced Performances towards Methanol Oxidation Reaction

Abstract

In this work, ternary TePbPt alloy nanotube(NT) catalyst was designed based on the following rational considerations. Pb and Te, which could facilitate removing adsorbed CO-like intermediate via bifunctional mechanism and adjusting electronic structure of Pt, respectively, were both introduced into the alloy NT catalyst. The as-designed alloy NT catalyst with uniform ultrathin and ultralong structure was prepared precisely through hard template method with pre-synthesized TePb nanowires as sacrificial template. The NT catalyst exhibits excellent performances for methanol oxidation reaction (MOR) both in activity and durability in acid medium. Further characterizations reveal that the enhanced performances should be due to the adjusted electronic and chemical structure of Pt via the interactions among Pt and Te, Pb according to complex mechanism, which was illustrated in details.
