ResumoCarbon nanospheres (CNS) were synthesized using bis(acaetylacetonato)oxovanadium(IV) as catalyst precursor in a traditional chemical vapor deposition (CVD) carbon nanotube synthetic reactor. The as-prepared products were characterized with Scanning electron microscope (SEM), Raman spectroscopy, High resolution transmission electron microscopy, (HR-TEM), Thermogravimetric analysis, (TGA), Powder X-ray diffraction, (PXRD) and Energy dispersive spectroscopy, (EDS). All indicate the presence of carbon nanospheres with uniform diameter, together with small amounts of carbon nanotubes and amorphous carbon.
