The efficient synthesis of reduced graphene oxide (RGO) nanosheets via a chemical reduction process of exfoliated graphene oxide (GO) nanosheets was performed by introducing sodium oxalate (Na2C2O4) as a reducing agent. This study aimed to investigate the effects of reduction time on the synthesized RGO, with GO being reduced at intervals of 0.5, 1, and 2 hours for RGO-1, RGO-2, and RGO-3, respectively. The carbon/oxygen atomic ratio of the synthesized RGO-3 was found to increase significantly from 2.16 to 6.32 after reduction, as determined by X-ray photoelectron spectroscopy (XPS). Morphological analysis of RGO-3, conducted using high-resolution transmission electron microscopy (HRTEM), revealed the formation of single-layer structures. Moreover, it was observed that the number of RGO layers decreased with increased reduction time. These results indicate that sodium oxalate plays a crucial role in the effective removal of oxygen-containing groups in GO, thus producing high-quality RGO suitable for various applications.
