摘要
选择合适的生物质材料是获得功能碳材料的有效途径之一。通过柠檬酸钾和三聚氰胺一步热解法制备了高氮掺杂多孔碳纳米纤维(NPCF)。在电流密度为0.1和1.0 A·g^(-1)时,NPCF电极的容量分别为218和140 mAh·g^(-1)。同时,具有NPCF阳极的钠离子电容器(SIC)在1.0 A·g^(-1)下表现出优异的倍率性能和超长的使用寿命,可循环超过2500次。
One of the effective approaches to obtaining functional carbon materials is selecting some appropriate biomass materials.In this work,the high nitrogen-doped porous carbon nanofibers(NPCF)can be obtained by onestep pyrolysis of potassium citrate and melamine.The NPCF electrode delivered capacities of 218 and 140 mAh·g^(-1) at current densities of 0.1 and 1.0 A·g^(-1),respectively.Concurrently,the sodium ion capacitors(SICs)with NPCF anode show outstanding rate performance and long lifespan for over 2500 cycles at 1.0 A·g^(-1).
