摘要
为了探索出一种可控、稳定、高效的制备碳纳米角的方法,采用高功率、短脉冲Nd∶YAG激光器对悬浮于液相介质中的天然鳞片石墨颗粒进行激光辐照,并通过高分辨率透射电镜、激光喇曼光谱等检测手段对实验产物进行表征,对实验结果进行了理论分析与实验验证。结果表明,激光能量为150mJ,300mJ,450mJ和600mJ时,对应的产物分别为seed型、bud型、dahlia型和petal-dahlia型碳纳米角;4种形态的碳纳米角的粒径均分布于10nm～80nm范围内,平均粒径分别为29nm,33nm,36nm和38nm。该研究对制备出不同形态的碳纳米角是有帮助的。
In order to explore a controllable, stable and efficient method for preparing carbon nanohorns, Nd∶YAG laser with high power and short pulse was used to irradiate natural flake graphite particles suspended in liquid medium. The experimental products were characterized by high resolution transmission electron microscopy and laser Raman spectroscopy. The experimental results were analyzed theoretically and experimentally. The results show that, when laser energy is 150 mJ, 300 mJ, 450 mJ and 600 mJ, the corresponding products are carbon nanohorns of seed type, bud type, dahlia type and petal-dahlia type respectively. The particle sizes of the four kinds of carbon nanohorns are all distributed in the range of 10 nm to 80 nm with average sizes of 29 nm, 33 nm, 36 nm and 38 nm, respectively. This study is helpful to prepare different forms of carbon nanohorn materials.
