Abstract
Core-shell nanoparticles having a solid core comprising a first metal and a shell comprising a second metal disposed at least a portion of the exterior surface of the core. The core-shell nanoparticles comprise a non-precious transition metal and the second metal comprises a precious metal or semi-precious metal. The core-shell nanoparticles can be used to catalyze oxygen reduction reactions. Also provided are compositions comprising the core-shell nanoparticles, methods of making same, and devices of same.
