One Step Synthesis of Reduced and Moringa oleifera Treated Graphene Oxide: Characterization and Antibacterial Studies

Abstract

Reduced graphene oxide (rGO) was synthesised by the direct one-step synthesis using modified Hummers method. Synthesized rGO was treated with Moringa oleifera plant extract (MO-rGO). The synthesized rGO and MO-rGO were characterised using Fourier Transform Infrared (FTIR), Raman spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) and High Resolution Transmission Electron Microscope (HRTEM) along with Energy Dispersive X-ray Spectroscopic analyses (EDS). The formation of rGO and MO-rGO were studied using XRD. The presence of functional groups and structural behaviour was studied using FTIR and Raman spectroscopic studies. It is observed that the functional groups are incorporated in the synthesized samples and found to be the formation of rGO. The morphology and elemental compositions of the synthesized rGO’s were studied using SEM, HRTEM and EDS, respectively. In order to understand the bacterial activity of synthesized rGO’s were tested against E. Coli and S. Aureus. The synthesized rGO’s shows the better efficiency than graphite.
