Recent years have witnessed many breakthroughs in research on graphene as well as a significant improvement in the electrochemical synthesis methods of graphene oxide (GO). GO is a derivative of graphene which has attracted the focus of worldwide scientists and researchers because of its hydrophilic and easily functionalized properties. The electrochemical approach is popular because it saves time, creates zero explosion risk, releases no hazardous gases, and avoids environmental pollution. Although recent publications show that the green, rapid, and mass electrochemical synthesis of GO has more advantages as compared with the traditional Hummers method, it is crucial to study the effects of reaction parameters. Herein, we review recent various works regarding the influences of various reaction parameters on the synthesis of GO sheets. The advancement, current challenges, and solutions of electrochemical synthesis methods of GO are also outlined. Through this review, we hope to spark some clear ideas for anyone who wants to scale up the yield of GO.
近年来,石墨烯研究取得了许多突破,氧化石墨烯(GO)的电化学合成方法也有了显著改进。GO是石墨烯的衍生物,因其亲水性和易于功能化的特性而吸引了全球科学家和研究人员的关注。电化学方法很受欢迎,因为它节省时间、无爆炸风险、不释放有害气体且避免环境污染。尽管最近的出版物表明,与传统的Hummers方法相比,绿色、快速且大规模的GO电化学合成具有更多优势,但研究反应参数的影响至关重要。在此,我们综述了近期关于各种反应参数对GO片材合成影响的各类研究工作。还概述了GO电化学合成方法的进展、当前挑战及解决方案。通过这篇综述,我们希望能为任何想要提高GO产量的人带来一些清晰的思路。
