The combustion synthesis method is actually used in the industrial mass production process of fullerenes. However, the fullerene formation mechanism from PAHs in a toluene and oxygen premixed flame has not been clarified yet. In the present research, fullerene contents and PAH contents in soot samples were investigated to clarify the formation mechanism of PAHs and fullerenes when the burner structure was changed in two kinds. In the case of the burner B the fullerene contents decreased remarkably and PAHs contents increased in comparison with the case of the burner A. These results showed that the heat supply and the temperature in the chamber were important factors in the fullerene formation mechanism in a flame.
