Preparation and characterization of carbon microspheres agglomerated from worm-like carbon nanomaterials

Conventional methods of preparing carbon nano in most cases prepare worm-like carbon nanomaterials in a single dispersed arrangement, agglomerated into a spherical worm-like carbon nano is more special and uncommon. Tetradecyl trimethyl ammonium bromide (TTAB) and potassium chloride were used as raw materials, and sphericity of worm-like carbon nano could be prepared by in situ carbonization method. This particular morphology is called worm-like carbon nanospheres. The yield of worm-like carbon nanospheres was calculated to be about 5‰ using tetradecyl trimethyl ammonium bromide as the carbon source. A series of characterization means such as SEM, FT-IR, Raman, XRD and XPS were used for characterization. The characterization results show that the size of worm-like carbon nanospheres is between 300 and 600 nm, relatively dispersed, and the aggregation phenomenon is not obvious. The structure of worm-like carbon nanospheres has some defects with graphitization degree ID/IG = 0.8. About the formation mechanism of worm-like carbon nanospheres is explained accordingly in the existing cases.
