초록

Twinning boundary-elongated hierarchical Pt nanostructures with excellent electrocatalytic activity were prepared by using axially twinned Pt3Ni nanorods as the platform for epitaxial transfer of a twinned crystal structure. The high electrocatalytic activity of the hierarchical nanostructures results from the synergistic effects of lattice mismatch between the Pt3Ni core and the Pt shell and the elongated twinning boundary.
