The synthesized materials were thoroughly characterized by X-ray diffraction (XRD) studies, Brunauer-Emmett-Teller (BET) analysis, transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, photoluminescence (PL) and UV-Visible spectroscopy. The nanocomposite was studied for its catalytic activity in degradation of methylene blue (MB) and reduction of 4-Nitrophenol (4-NP) to 4-Aminophenol (4-AP). The observed results of catalytic efficiency and rate constants indicated that the NRGO-CoWO<inf>4</inf>-Fe<inf>2</inf>O<inf>3</inf> nanocomposite can perform as an excellent catalyst compared to other composite materials. The detailed experimental study revealed that this ternary nanocomposite shows a great promise as a candidate for various environmental applications. © 2018 Elsevier B.V.Aromatic compoundsCatalyst activityCatalystsDoping (additives)Electron microscopyGrapheneHigh resolution transmission electron microscopyIron oxidesNanocompositesOrganic pollutantsRate constantsReductionTungsten compoundsUltraviolet visible spectroscopyX ray diffractionBrunauer emmett tellersCatalytic efficienciesDye degradationEnvironmental applicationsMethylene BlueNRGOReduced graphene oxidesUV visible spectroscopyX ray photoelectron spectroscopyNovel NRGO-CoWO4-Fe2O3 nanocomposite as an efficient catalyst for dye degradation and reduction of 4-nitrophenol
