| 摘 要： | Nitrogen(N)-doped carbon nanosheets(TCM-900) were prepared by pyrolyzing the cobalt metal organic framework(MOF) and acid treatment.The TCM-900 showed outstanding ORR performance with half-potential of 0.805 V.The density function theory(DFT) reveals the nitrogen activates the carbon atoms in the framework.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
