控制石墨烯结构的规模化制备将显著提高其商业可行性。尽管在这一领域进行了大量的研究，但无缺陷石墨烯（df-G）的尺寸控制，而没有任何氧化或结构损伤的痕迹仍然是一个关键的挑战。在这里，我们提出了一种新的可扩展的路线，通过在低温下顺序插入钾和吡啶来产生亚微米至微米尺寸可控的df-G。结构和化学分析证实，df-G完美地保留了石墨烯的固有性质。03 - 04陈晓（
The scalable preparation of graphene in control of its structure would significantly improve its commercial viability. Despite intense research in this area, the size control of defect-free graphene (df-G) without any trace of oxidation or structural damage remains a key challenge. Here, we propose a new scalable route for generating df-G with a controllable size of submicron to micron through sequential insertion of potassium and pyridine at low temperature. Structural and chemical analyses confirm that the df-G perfectly preserves the intrinsic properties of graphene. The Co3O4 (
