The effects of active species and by-products on the rapid synthesis of nano-graphene by in-liquid plasma irradiation in alcohol were investigated. While the synthesis rate was constant independent of irradiation time, the by-product peak increased remarkably and the emission intensity of C₂ peak was also constant. On the other hand, the OH emission peak intensity decreased, while the full width at half maximum of the G band peak in the Raman spectrum increased. These results suggest the contribution of C₂ and OH radicals to the synthesis rate and crystallinity, respectively.
