Pretreatment impact on electrochemically synthesized graphene oxide

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.
