氧化插层是目前制备氧化石墨烯(GO)类单层/多层材料的主流方法之一, 其关键步骤为氧化剂和插层剂的选择及工艺的匹配。传统工艺主要采用Hummers法, 存在氮氧化物排放量大、环境危害大、安全性差等问题, 本文综述了近年来氧化插层制备氧化石墨烯的研究进展, 重点阐述了绿色氧化剂、插层剂的研究进展及相应工艺的改良与创新, 系统分析了不同试剂的反应机理及应用效果, 旨在寻找绿色环保、价格低廉、更适合工业化的制备方法。

Oxidation intercalation is one of the mainstream methods to prepare graphene oxide (GO) monolayer/multilayer materials. The key steps are oxidation agent and intercalation agent selection and process matching. The traditional process maily uses Hummers method which has problems such as large amount of nitrogen oxide emissions, significant environmental hazards and poor safety. In this paper, the research progress of graphene oxide prepared by oxidation intercalation in recent years was reviewed. The green oxidantion agent, intercalation agent research progress and corresponding process improvement and innovation were emphatically expounded. The reaction mechanism and application effect of different agents were systematically analyzed, aiming to find a green, low-cost and more suitable preparation method for industrial production.
