以静电纺丝技术构筑的SnO₂纳米管为模板，在其表面制备金属有机框架层，并进一步通过硒化反应制备了ZnSe/CoSe/SnO纳米颗粒嵌入的N掺杂多孔碳纳米管（ZCS@NCNTs）。结果表明，以ZCS@NCNTs作为锂离子电池负极材料时展现出独特的结构和组分优势，显示出高倍率性能以及优异的循环稳定性，在电流密度为0.1 A/g时循环100圈的比容量为1 621.6 mAh/g；在5 A/g下循环2 000圈后仍能提供426.2 mAh/g的可逆容量。

Metal-organic frameworks (MOFs) layer is prepared on the surface of SnO₂ nanotubes constructed by the electrospinning technology, and further prepared into nitrogen-doped porous carbon nanotubes embedded with ZnSe/CoSe/SnO nanoparticles (ZCS@NCNTs) through selenization reaction.ZCS@NCNTs, as anode materials of lithium ion battery, exhibits unique structural and component advantages, showing high rate performance and excellent cycling stability.Its specific capacity is 1 621.6 mAh·g^-1 after 100 cycles at a current density of 0.1 A·g^-1, and its reversible capacity remains 426.2 mAh·g^-1 after 2 000 cycles at 5 A·g^-1.
