Claims9
A particle, comprising:
- a supported Ni/Pt bimetallic nanoparticle prepared by a process comprising heating a powder of an Al2O3-supported crystalline Ni nanoparticle to about 200 to 500° C. under hydrogen flow for about 1 to 5 hours to form a nickel hydride layer on the surface of the Ni nanoparticle (Nis—H) and mixing the Al2O3-supported Nis—H powder with a first solution including Pt(acac)2 for about 10 to 30 hours under hydrogen, wherein the supported Ni/Pt bimetallic nanoparticle has a monolayer of Pt atoms disposed on the surface of the Ni nanoparticle, wherein the supported Ni/Pt bimetallic nanoparticle has a molar ratio of Pt atoms to Ni surface atoms (Pt/Nis) of 0.1 to 0.94.
