The　electro-catalytic　performance　of　the　bi-functional　catalysts　at　the　air　cathode　for　the　oxygen　evolution　reaction　(OER)　and　oxygen　reduction　reaction　(ORR)　plays　a　significant　role　for　the　development　of　rechargeable　zinc　air　batteries　(ZABs).　To　obtain　the　high-performance　electrocatalysts,　a　series　of　porous　Co(3)O(4)samples　derived　from　zeolitic　imidazolate　framework-67　(ZIF-67)　are　prepared　by　one-step　annealing　process　at　different　temperature　(350,　450,　and　550　degrees　C)　under　air　atmosphere.　Compared　with　the　commercial　Co3O4,　the　optimized　sample　Co(3)O(4)prepared　at　450　degrees　C　(CO3O4/C-450)　exhibits　the　lowest　overpotential　of　1.68　V　and　the　highest　half-wave　potential　of　-　0.56　V　because　the　porosity　of　as-prepared　Co(3)O(4)provides　abundant　reactive　sites.　Moreover,　the　high　discharge　potential　of　1.33　V　and　long　cycle　life　of　more　than　100　h　at　20　mA　cm(-2)are　achieved　in　ZABs　with　CO3O4/C-450　electrocatalyst,　which　are　attributed　to　the　better　stability　provided　by　the　carbon　coating.
