Bioinspired reduced graphene oxide nanosheets using Terminalia chebula seeds extract

• A green eco-friendly synthesis method for T. chebula mediated reduced graphene oxide.
• HPLC, FTIR and Raman results explained the stabilization of graphene sheets.
• Adsorption of polyphenols on the surface of graphene sheets stabilizes it.

A green one step facile synthesis of graphene nanosheets by Terminalia chebula (T. chebula) extract mediated reduction of graphite oxide (GO) is reported in this work. This method avoids the use of harmful toxic reducing agents. The comparative results of various characterizations of GO and T. chebula reduced graphene oxide (TCG) provide a strong indication of the exclusion of oxygen containing groups from graphene oxide and successive stabilization of the formed reduced graphene oxide (RGO). The functionalization of reduced graphene oxide with the oxidized polyphenols causes their stability by preventing the aggregation. We also have proposed how the oxidized polyphenols are accountable for the stabilization of the formed graphene sheets.

A simple and efficient method for the reduced graphene oxide production by the eco-friendly deoxygenation of graphene oxide using the seed extract of T. chebula. The phytochemicals in the T. chebula extract are responsible for the reduction and also stabilizes by functionalizing on the surface of the graphene sheets.Figure optionsDownload as PowerPoint slide
