The thermal properties of bimetallic Pt nanowires have been investigated using classical interatomic potentials. Edge decorated Pt nanowires may improve the inter-facet exchange of reaction intermediates resulting in improved oxygen reduction reaction activities at fuel call cathode electrodes. In this work we report on the melting behaviour of Pt-based nanowires where either an edge atomic row or atomic shell of Pt nanowires are substituted by Au, Ag or Pd. Our overall intention is to find...
