In Situ Fabrication of PtCo Alloy Embedded in Nitrogen‐Doped Graphene Nanopores as Synergistic Catalyst for Oxygen Reduction Reaction

Abstract

In situ fabrication of a PtCo alloy etched and embedded in nitrogen-doped graphene nanopores (PtCo/NPG) serve as high-performing electrocatalysts for the oxygen reduction reaction (ORR). Density functional theory calculations indicate that the nanopores in NPG can not only stabilize PtCo nanoparticles but can also change the electronic structures of PtCo, thereby enhancing ORR performance.
