摘要
The N,S co-doped porous carbon nanofibers were fabricated by the carbonization of[Zn_(2)(tdc)_(2)(MA)]n MOFs/polyacrylonitrile nanofibers composite,which was produced by the electrospinning technology.The electrochemical results show that the N,S co-doped porous carbon nanofibers can achieve capacity of 201.2 mAh·g^(-1)at the current density of 0.05 A·g^(-1).Furthermore,the reversible capacity still has 161.3 mAh·g^(-1)even at a high current density of 1 A·g^(-1)after 600 cycles.The superior electrochemical performance shows that the N,S co-doped porous carbon nanofibers electrode material can be used as an ideal anode material for sodium-ion batteries.
通过静电纺丝技术,将制备的[Zn_(2)(tdc)_(2)(MA)]nMOFs与PAN基纳米纤维复合,在N_(2)气氛中高温碳化处理制得一种氮硫共掺杂多孔碳纳米纤维材料。电化学测试结果表明,氮硫共掺杂多孔碳纳米纤维材料在0.05 A·g^(-1)电流密度下,可逆容量达到201.2 mAh·g^(-1)。在1 A·g^(-1)的电流密度下循环600圈后其可逆容量为161.3 mAh·g^(-1)。此氮硫共掺杂多孔碳纳米纤维电极材料的优越电化学性能可作为钠离子电池负极材料的一种理想选择。
