| Abstract: | Troilite balls were synthesized by arc discharge method with pyrite catalyst in this work. The diameter of troilite balls is about 3mm. Carbon filaments and hollow carbon balls were found on the surface of troilite balls. It was confirmed by SEM, TEM and EDX measurements. The shape of carbon filaments looks like "Y" or "T", and we did not find clear double layer structure in the carbon filaments. It was proposed that pyrite catalyze the formation of carbon nanotubes, carbon filaments and carbon balls. |
