以煤焦油为碳源,三聚氰胺为氮源,MgO 纳米片为模板,通过预氧化和炭化过程合成出氮掺杂中孔炭纳米片(NMCNs),可实现对中孔炭材料的孔结构和氮掺杂含量的调控。所制中孔炭材料具有独特的中孔和片状结构,比表面积较大(1209 m2/ g),氮掺杂量较高(8.6%)。将其应用于锂离子电池负极材料,NMCNs 展现出比容量高和循环稳定性优良的特性,在电流密度为100 mA/ g 时具有高达1000 mAh/ g 的比容量。
Nitrogen-doped mesoporous carbon nanosheets (NMCNs) were prepared from coal tar and melamine using a layered MgO as template. Porous structures and nitrogen doping levels were readily tuned by adjusting experimental parameters. NMCNs show high specific capacities and excellent cyclic stabilities as anode materials for lithium ion batteries. A sample prepared under op-timum conditions shows a high reversible capacity of nearly 1 000 mAh/ g at a current density of 100 mA/ g, which can be ascribed to its unique mesoporous sheet-structure, a high specific surface area of 1 209 m2 / g, and a uniform and high bulk nitrogen content of 8. 6% . Our work demonstrates that coal tar can act as an excellent carbon source for the production of carbon materials with high performance in lithium-ion batteries.
