Abstract:
A method for synthesis of PtNi nanocages by synthesizing Pt1Ni6 nanoparticles and acid leaching to form PtNi nanocages. The acid leaching removes nickel selectively from the core of the nanoparticle.

Claim (Index 10):
A method of synthesizing PtNi nanocage catalyst comprising the steps of:\n synthesizing Pt 1 Ni 6  nanoparticles having a Pt shell and a Ni core by:\n mixing a nickel precursor, a surfactant, a platinum precursor, and a polar solvent to form a reaction solution, the ratio of nickel precursor to platinum precursor being 10:90 to 40:60; \n holding the solution at a temperature of at least at a temperature of at least 110\u00b0 C. to remove dissolved oxygen; \n heating the solution to at least 230\u00b0 C. for at least 30 minutes and forming a Pt 1 Ni 6  nanoparticle solution; \n acid leaching the Pt 1 Ni 6  nanoparticles by:\n mixing an acid with the Pt 1 Ni 6  nanoparticle solution at temperature above 80\u00b0 C.; \n removing Ni from the nanoparticles to form nanocages; and \n collecting the nanocages.
