The　rational　construct　of　bifunctional　electrocatalysts　with　high　active　and　excellent　cycling　durability　is　the　top　priority　for　oxygen　reduction　reaction　(ORR)　and　oxygen　evolution　reaction　(OER).　Recently,　metal-nitrogen-doped　carbon　(M-N-C)　components　formed　by　transition　metal　(TM)　combined　with　nitrogen-doped　carbon　materials　have　drawn　extensive　interests　due　to　their　inexpensive　cost　and　great　activity.　Herein,　a　straightforward　evaporation-pyrolysis　strategy　is　designed　for　the　preparation　of　3D　hierarchical　electrocatalyst　(abbreviated　as　Co@N–HCCs@NG,　which　represented　carbonization　products　at　900　°C)　made　of　nitrogen-doped　hollow　carbon　nanocapsules　combined　with　Co　nanoparticles　bridged　N-doped　graphene　by　carbonization　of　a　pristine　ZIF-67/GO,　enables　hierarchical　porous　structure,　high　surface　area　(618.12　m2　g-1)　and　a　hollow　capsule-like　nanostructure.　Of　these,　the　Co@N–HCCs@NG　composite　displays　outstanding　electrocatalytic　performances　for　OER　(overpotential　of　298　mV　@　10　mA　cm-2)　and　ORR　(0.86　V　@　E1/2)　in　alkaline　electrolyte,　which　could　rival　the　most　of　reported　materials.　The　tactics　presented　in　this　research　may　provide　a　powerful　platform　to　engineer　non-precious　highly　electroactive　catalysts　with　a　well-excogitated　structure　and　preferable　activity　for　clean　energy　conversion　technologies.　©　2021　Elsevier　Ltd
