| Abstract: | 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. |
