In‐Liquid Plasma Synthesis of Nanographene with a Mixture of Methanol and 1‐Butanol

In-liquid plasma synthesis of high-crystallinity nanographene is realized by use of a mixture of methanol and 1-butanol. The synthesized nanographene crystallinity correlated with the ratio of molar concentrations of carbon over oxygen (C/O) of the mixing alcohol, i. e., the amount of hydroxyl groups in the liquids, which could be optimized by tuning the mixing ratio. This opens a new synthesis route for high-quality graphene nanomaterials at nearly room temperature. More information can be found in the Full Paper by Kenji Ishikawa et al.
