In the high-speed synthesis process of nanographen with high crystallinity by in-liquid plasma, the effect of hydroxyl group in synthesis mechanism was clarified from comparison of alcohols and hydrocarbons as raw materials. In the case of alcohols containing a hydroxyl group, although the synthesis rate decreased, nanographene having higher crystallinity was synthesized. These results suggest the selective removal of amorphous components by oxygen atoms derived from hydroxyl groups.
