Abstract

The production of graphene oxide by the electrochemical method is more environmentally friendly, faster and suitable for mass production than the chemical method. Although this technique is very practical, the correct parameters must be selected to produce graphene oxide. Therefore, it is very important to investigate the factors affecting graphene oxide synthesis in the electrochemical process. In this study, the effect of pretreatment on graphene oxide produced by the electrochemical method was investigated. Structural characterization of the produced graphene oxide was carried out using X-ray diffraction, Raman spectroscopy and energy-dispersive X-ray spectroscopy, while morphological research was performed using scanning electron microscopy. Due to the increase in the electrochemical oxidation performance of dilute nitric acid with the effect of the pretreatment process, an effective increase in the oxygen content in the structure of graphene oxide was detected.
预处理对电化学合成氧化石墨烯的影响
电化学法制备氧化石墨烯比化学法制备氧化石墨烯更环保、速度更快、适合批量生产。虽然这项技术非常实用,但必须选择正确的参数才能生产氧化石墨烯。因此,研究电化学过程中影响氧化石墨烯合成的因素是十分重要的。本研究考察了预处理对电化学法制备氧化石墨烯的影响。利用x射线衍射、拉曼光谱和能量色散x射线光谱对制备的氧化石墨烯进行了结构表征,并利用扫描电镜进行了形态研究。由于预处理工艺的作用提高了稀硝酸的电化学氧化性能,因此检测到氧化石墨烯结构中的氧含量有效增加。
