First claim
Opening claim text (preview).
The invention claimed is: 1. A nanoparticle, comprising: an intermetallic core comprising a first metal and a second metal, wherein the first metal is palladium and the second metal is at least one of cobalt, iron, nickel, or combination thereof, and the first metal and the second metal are ordered into different distinct sites of the intermetallic core; and a shell comprising palladium and gold. 2. The nanoparticle of claim 1 , wherein at least parts of the intermetallic core comprises a trigonal symmetry. 3. The nanoparticle of claim 1 , wherein at least parts of the intermetallic core comprises a rhombohedral symmetry. 4. The nanoparticle of claim 1 , wherein the nanoparticle has an average diameter of between about 2 nm and about 10 nm. 5. The nanoparticle of claim 1 , wherein the second metal is cobalt. 6. The nanoparticle of claim 1 , wherein the shell is conformal with the intermetallic core.
