Graphene oxide (GO) is a promising material useful in energy storage applications, sensors, supercapacitors, solar cells, and biomedical applications. However, the mining process of graphite as raw material for GO is complicated and can harm the environment and local communities. Besides, GO is currently regarded as an expensive material due to its complicated manufacturing method and limited production capacity. For this purpose, recovered carbon black (rCB) of waste was used to synthesize GO by utilizing the modified Hummers method and characterized by Raman spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and field emission scanning electron microscope (FESEM). Raman analysis showed D-band peaks at 1359 cm-1, 1357 cm-1, and 1355 cm-1 and G-band peak at 1618 cm-1, 1585 cm-1, and 1583 cm-1 for GO-1%, GO-3%, and GO-5% respectively indicate the successful synthesis of GO. The intensity ratio (Id/Ig) of GO-3% was the highest with Id/Ig of 0.82 indicating the highest oxidation degree. The FT-IR spectroscopy showed the presence of OH, C=O, and C-O stretching vibrations on the structure of GO-1%, GO-3%, and GO-5%, suggesting successful of oxidation process in converting rCB to GO. XRD analysis shows the peak appear at 2θ = 25.33°, 25.54°, and 25.56° for GO-1%, GO-3%, and GO-5% respectively. Moreover, FESEM analysis shows that the smallest mean particle size was obtained for GO-3% at the range of 20~40 nm. © Malaysian Journal of Microscopy (2024). All rights reserved.
