Özet
It is possible to produce graphene nanosheets with the electrochemical exfoliation method. Despite the many advantages of this method, due to the nature of the process, it causes many defects in graphene. These defects, on the other hand, negatively affect the electronic properties of graphene. For this reason, in this study, a method that can reduce the destructive effects of the electrochemical method on graphene has been proposed. Herein, the electrolyte has been modified with hydrogen peroxide in the electrochemical exfoliation process, and its effect on graphene has been investigated. Structural properties, X-ray diffraction, Raman spectroscopy, energy-dispersive X-ray spectroscopy, and morphological features also were performed using scanning electron microscopy. The results were discussed by comparing them with each other and with the literature. Accordingly, it was found that when the electrolyte, which is one of the components of the electrochemical process, is modified with hydrogen peroxide, there is an effective decline in the defect density of the graphene produced. In addition, a significant decrease in the number of layers of graphene produced in the presence of hydrogen peroxide was detected.
