In the present work, reduced graphene oxide was obtained by green synthesis, using extracts of (gobernadora) and (habanero). Graphene oxide was synthesized by the modified Hummers' method and subsequently reduced using natural extracts to obtain a stable and environmentally friendly graphene precursor. Consequently, the gobernadora aqueous extract was found to have a better reducing power than the habanero aqueous extract. This opportunity for green synthesis allows the application of RGO in photocatalysis for the degradation of the methylene blue dye. Degradation efficiencies of 60% and 90% were obtained with these materials.
