摘要 采用射频等离子体增强化学气相沉积技术,在CH4/H2的气氛中合成了非晶空心碳球.利用SEM,TEM,拉曼光谱对样品的形貌、成分和结构进行了表征.非晶空心碳球的直径在100～800nm之间,分布在弯曲的碳纳米管丛中.非晶空心碳球的生长机制可能为膨胀生长. Amorphous hollow carbon spheres were synthesized using RF-PECVD in mixed CH4/ H2 gases. The products were characterized by scanning electron microscope, Raman spectroscopy, and transmission electron microscopy. Diameters of amorphous hollow carbon spheres were 100 800 nm, which were dispersed among bent graphitized carbon nanotubes. A possible formation mechanism of the amorphous hollow carbon spheres was expansive growth.
