In this work, graphene oxide (GO) and ZnO were synthesized using the modified Hummers method and the Spanhel and Anderson method, respectively. ZnO/GO composites were then successfully synthesized using a fast and direct process. The results of the X-ray diffraction, scanning electron microscopy (SEM), Raman spectroscopy, and Fourier-transform infrared spectroscopy (FTIR) proved the conversion of GO to reduced graphene oxide, without additional chemical agents or processing at high temperatures and under high vacuum. This study reveals the interaction between oxide materials, which can be of help in the field of electronic microdevice manufacturing.
