UV-Visible, FTIR and Electrochemical Properties of rGO and ZnO/rGO Nanocomposite Produced via Green Synthesis Process

In this study, we explored the synthesis of reduced graphene oxide (rGO) and rGO/zinc oxide (rGO/ZnO) nanocomposites derived from graphene oxide (GO) in an eco-friendly approach. Using Hummers method, we successfully synthesized GO, which was subsequently reduced to rGO using Tinospora Cordifolia plant extract. Furthermore, a novel one-pot synthesis method employing the plant extract was employed to fabricate rGO/ZnO nanocomposites. Optical study using UV-visible spectroscopy, vibrational analysis using Fourier Transform Infrared Spectroscopy (FTIR), and electrochemical evaluation using cyclic voltammetry (CV) were among the extensive characterizations performed on the synthesised materials. The characterization results unequivocally confirmed the formation of GO, its reduction to rGO, and the successful synthesis of rGO/ZnO nanocomposites. This study not only demonstrates the viability of green reducing agents in the fabrication of advanced nanomaterials but also underscores the importance of sustainable practices in contemporary materials research. The findings presented herein not only contribute to the expanding knowledge of green synthesis methodologies but also offer a promising pathway for future environmentally conscious research and technological advancements.
