Multiply twinned Pt-Pd nanoicosahedrons as highly active electrocatalysts for methanol oxidation

Bimetallic Pt-Pd nanoicosahedrons (NIs) with multiple {111} twins were obtained through a facile one-pot hydrothermal synthesis in a high shape selectivity of 82%. The {111}-enclosed NIs exhibited superior electrocatalytic activities to {111}-enclosed Pt-Pd nano-tetrahedrons as well as commercial Pt catalysts (Pt black and Pt/C) for methanol oxidation.
