Here, we demonstrate that Cobalt/cobalt oxide core-shell nanoparticles integrated on nitrogen-doped three-dimensional graphene architecture (Co/CoO-NG) were synthesized through a facile hydrothermal method following by heat treatment. The unique endurable porous structure could provide sufficient mass transfer channels and ample active sites on Co/CoO-NG to facilitate the catalytic reaction. The synthesized Co/CoO-NG was explored as an electrocatalyst for the oxygen reduction reaction, showing comparable oxygen reduction performance with excellent methanol resistance and better durability compared with Pt/C.
