Paper Title:
Synthesis of Hollow Carbon Hemispheres in the Magnesium Carbonate-Metallic Li System with the Help of CHBr3
  Abstract

Hollow carbon hemispheres (HCHs) were synthesized at 500 oC in the magnesium carbonate-metallic Li system with the help of CHBr3. The product was characterized by X-ray diffraction (XRD), transmission electron microscope (TEM) and field emission scanning electron microscope (FESEM). XRD and electron diffraction (ED) pattern results showed that HCHs were graphite phase and polycrystalline. By FESEM and TEM observation, the diameters of the HCHs were in the range of 200-900 nm. The shell of the HCHs was single-layer and their thickness was about 31 nm. The formation mechanism of HCHs with the help of CHBr3 was discussed. Besides, the effect of reaction temperature and dosage of CHBr3 on the morphology of HCHs was studied.
