摘要：

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. © 2015 Wiley-VCH Verlag GmbH & Co.
