摘要
采用不同的工艺方法对石墨进行氧化合成氧化石墨(GrO)。在本章中,我们描述了一种基于Hummers方法的简单合成路线,而不使用NaNO 3获得几乎相同的结果,该方法旨在高质量地大规模生产GrO,与传统的和改进的Hummers方法获得的GrO具有相似的性质。通过一系列间歇反应得到GrO,并采用不同的技术对其进行了表征,结果表明层间D -空间、氧官能团的类型和含量以及I - D /I - G比相同。该方法的高重复性为氧化石墨烯的大规模生产提供了一种有效的替代方法。
Graphite Oxide: A Simple and Reproducible Synthesis Route
The synthesis of graphite oxide (GrO) by oxidation of graphite has been carried out by different procedures. In this chapter, we describe a simple synthesis route based on Hummers’ method without the usage of NaNO 3 achieving nearly the same outcomes, and this methodology is directed toward high-quality scale production of GrO with similar properties compared with GrO obtained with traditional and improved Hummers’ methods. The GrO was obtained in a series of batch reactions and characterized by different techniques, and the results showed identical interlayer d-space , type and content of oxygen functionalities, and I D /I G ratio. The high reproducibility of this methodology offers an efficient alternative for the large-scale production of graphene oxide.
