Abstract: An eco-friendly process of reduction of graphene oxide using aqueous extract of Amaranthus dubius under refluxing method is herein reported. The colour change of the graphene oxide (GO) solution from brown to black was noted during the reduction of graphene oxide. UV-Visible spectrophotometer was used to monitor the formation of reduced graphene oxide (AKRGO). The crystallite size of nanographene was confirmed by XRD analysis and Scherrer’s formula. FTIR spectral analysis revealed the reduction of graphene oxide using aqueous extract of Amaranthus dubius. The morphology of the synthesized graphene was examined by SEM analysis.
