摘 要: 采用氮含量更高的乙二胺为催化剂,同时采用高氮含量的3-氨基苯酚为氮源,开发了一种新型高效制备氮掺杂碳纳米粒子的技术,其所制备的碳纳米粒子具有较高的氮元素含量。实验结果表明,通过调控催化剂的浓度可以有效地控制纳米粒子的大小,其粒径在50~1 450 nm范围内有效可控。经过高温碳化所制备的杂化碳纳米粒子中的氮含量保持较高水平,其氮元素含量高达11.40 wt%。电化学测试结果表明,所制备得到的杂化碳球还表现出较高的比电容量。 A facile method is developed for synthesizing high nitrogen content carbon spheres.By using 3-aminophenol as precursor and ethylenediamine as the sole catalyst,higher nitrogen-doped resin and carbon particles are obtained.The resulting resin particles are spherical and uniform in size.The particle size is tunable from 50 to 1 450 nm by appropriately varying the concentration of catalyst.After carbonizing,uniform spherical carbon particles are also obtained with nitrogen content reaching up to 11.40 wt%.In the application of supercapacitors,the nitrogen-doped carbon spheres also exhibit superior performance,which shows high capacitance and excellent capacitance.
