In　this　work,　a　series　of　metallic　Co-ZnO　encapsulated　in　N-doped　carbon/carbon　nanotubes　(Co-ZnO@NC/CNT-T)　for　the　electrochemical　oxygen　reduction　reaction　(ORR)　were　synthesized　by　annealing　bimetallic　metal-organic　frameworks　(MOFs)　containing　Co　and　Zn　in　N-2　atmosphere.　Within　the　hybrid,　metallic　Co　was　integrated　with　ZnO　and　encapsulated　by　NC,　while　coral-like　CNTs　grew　out　of　the　obtained　Co-ZnO@NC　nanoparticles.　When　applied　in　ORR　catalysis,　the　optimized　Co-ZnO@NC/CNT-700　obtained　in　700　degrees　C　displayed　a　half-wave　potential　of　similar　to　0.86　V　and　a　limiting　current　density　of　similar　to-5.98　mA　cm(-2),　which　were　even　superior　to　20　wt%　Pt/C.　Further　results　demonstrated　that　the　presence　of　ZnO　was　closely　related　with　the　high　ORR　catalytic　activity　from　two　aspects.　(i)　ZnO　catalyzed　the　formation　of　Co-0,　Co2+,　pyridinic　and　graphitic　N　as　the　main　active　species　for　ORR.　(ii)　ZnO　promoted　the　growth　of　CNTs　and　micro/mesoporous　structure,　which　improved　the　electrochemical　active　surface　area　(ECSA)　and　mass　transfer　during　the　ORR　process.
