Phytosynthesis and Characterization of Reduced Graphene Oxide using Aqueous Extract of Zingiber officinale and Brassica nigra

Abstract

Nowadays, graphene-based materials are receiving a great interest in the scientific community. The present work describes a novel method of synthesis of reduced graphene oxide (rGO). The Graphene oxide (GO) was prepared using a modified Hummers method. The GO was then reduced using the aqueous extract of Zingiber officinale and Brassica nigra by refluxing method. The reduction of GO was observed by changes in color from dark brown to black and then confirmed using UV-Visible spectral analysis. Surface Plasmon resonance for GO, Z-rGO and B-rGO were observed at 224[Formula: see text]nm, 344[Formula: see text]nm and 339[Formula: see text]nm, respectively. The morphology of the synthesized rGO were analyzed by scanning microscope. The stretching and vibrational mode were studied using FTIR analysis. The physical nature of the GO and rGO were examined using XRD. The synthesis of graphene using phytoextract as a reducing agent involves the simplistic and environmentally friendly approach.
