| 中文摘要: |
| 以三乙炔基取代三嗪为反应前体，以醋酸铜为催化剂，研究了三嗪取代石墨炔（T-GDY）的两相合成方法，并对其储钠性能进行了研究。该方法所用反应前体能够在水和有机相的两相界面处与催化剂接触从而高选择性反应并生成T-GDY。所制备的T-GDY具有大量的活性异原子中心和均匀孔道构造，能够为钠离子提供大量的存储位点和传输通道。基于T-GDY的钠离子电池在100 mA g-1的电流密度下表现出了550 mA h g-1高比容量，在2000 mA g-1的电流密度下循环1000圈，仍有95%的容量保持率，展现出良好的储钠应用前景。此外，该合成方法还具有温和的反应条件、催化剂廉价、操作简便等优势，为石墨炔类衍生物的制备和性质研究提供了一种可行的研究方向。 |
| 英文摘要: |
| Using tri-ethynyl-substituted triazine as reaction precursor and cupric acetate as catalyst, triazine-substituted graphdiyne (T-GDY) was prepared by interfacial synthesis method, and the sodium storage properties of T-GDY were studied. The used precursor can contact the catalyst at the water and organic interface, so as to react selectively and generate T-GDY. The prepared T-GDY has a large number of active heteroatomic centers and uniform pore structures, which can provide abundant storage sites and sufficient transport passageways for sodium ions. The sodium ion batteries based on T-GDY delivered a high specific capacity of 550 mA h g-1 under 100 mA g-1, and a 95% capacity retention after 1000 cycles at 2000 mA g-1 can be obtained, exhibiting a promising application prospect in sodium storage. In addition, this synthetic method also has the advantages of facile reaction conditions, cheap catalyst and simple operation, which provides a feasible research direction for the preparation and properties of graphdiyne derivatives. |
