▎ 摘　　要

Silver nanowires were embedded in N-doped graphene sheets to increase the accessible surface area of N-doped graphene and facilitate O-2 diffusion and OH- transport by creating porous channels within the graphene sheets. Our study showed that N-doped graphene-silver nanowire composites exhibited better electrochemical properties in the oxygen reduction reaction than individual N-doped graphene and silver nanowires.
