Segregation induced core-shell structure
Abstract
A process for synthesis of PtNi high surface area core/shell particles. The processing including formation of PtNi nanoparticles, exposure of the PtNi nanoparticles to oxygen to form a nickel oxide coating on the nanoparticles at the same time the segregation of Ni to surface induces a Pt-skin with PtNi core structure, removal of the nickel oxide coating to form PtNi core/Pt shell (or Pt-skin) structure.
