Abstract Herein, we proposed a novel approach to prepare the graphene with high quality, which was realized by exfoliating the KOH-etched graphite in H2O2 solution under microwave irradiation. The as-prepared graphene exhibits a smooth and transparent feature, and possesses high electrical conductivity of up to 2 × 105 S m−1. Compared with the conventional oxidation-reduction method, the present method is significantly efficient, and, most importantly, does not involve the use of acid and strong oxidizing agent, which will make it more competent in the scalable production of graphene.

一种制备高质量少层石墨烯的新颖有效方法

摘要 在此，我们提出了一种制备高质量石墨烯的新方法，该方法是通过在微波辐射下在 H2O2 溶液中剥离 KOH 蚀刻的石墨来实现的。所制备的石墨烯具有光滑透明的特征，并具有高达 2 × 105 S m-1 的高电导率。与传统的氧化还原方法相比，本方法具有显着的效率，最重要的是不涉及酸和强氧化剂的使用，这将使其更能胜任石墨烯的规模化生产。
