摘      要：Nitrogen(N)-doped carbon nanosheets(TCM-900)were prepared by pyrolyzing the cobalt metal organic framework(MOF)and acid *** TCM-900 showed outstanding ORR performance with half-potential of 0.805 *** density function theory(DFT)reveals the nitrogen activates the carbon atoms in the *** homemade ZAB with TCM-900 as ORR electrocatalyst exhibits high-power density of 45 mW·cm^(-2) and excellent long recharge cycling stability compared to Pt/C at 10 mA·cm^(-2).This work illustrates an attractive future of the rechargeable ZAB.
