以苯二甲酸-锌配位化合物(MOF-5)为原料合成金属骨架有机多孔碳MOF-PC,并首次应用于锂空气电池.采用XRD、SEM、TEM、氮气脱吸附和恒流充放电测试研究了MOF-PC的物理及电化学性能.结果表明,样品MOF-PC为无定型碳,比表面积为654m2g-1.以MOF-PC为空气电极的锂空气电池在0.1mA cm-2电流密度下放电比容量高达3 183mA h g-1,比传统碳材料Super P在相同电流密度下的放电比容量高90%.
The metal framework organic porous carbon (MOF-PC) was synthesized from phthalic acid-zinc complex (MOF-5) and applied to lithium-air battery for the first time. XRD, SEM, TEM, nitrogen desorption and constant current charge-discharge The physical and electrochemical properties of MOF-PC were studied.The results showed that the sample MOF-PC was amorphous carbon with a specific surface area of 654m2g-1.The lithium-air battery with MOF-PC as the air electrode exhibited good electrochemical performance at 0.1mA cm-2 current density The discharge capacity is up to 3 183 mA h g-1, which is 90% higher than that of the traditional carbon material Super P at the same current density.
