Cinnamon supported facile green reduction of graphene oxide, its dye elimination and antioxidant activities

A simple and efficient method of reduction for the preparation of reduced graphene oxide (rGO) from graphene oxide (GO) using Cinnamon (Cinnamomum zeylanicum) extract is reported. The reduction of GO was confirmed by XRD, TEM and UV-visible techniques. The rGO has shown to possess significantly high dye removal property of Malachite green (MG) and Methylene blue (MB) dyes in the absence of UV or Sun light. Further, it showed considerable antioxidant activity against scavenging of 1, 1-Dipheny1-2-picrylhydrazyl (DPPH) free radicals. The study illustrates an environment friendly green method for the efficient reduction of GO. (C) 2015 Elsevier B.V. All rights reserved.
