The structural properties of the product was investigated by X-ray diffraction (XRD), N2 adsorption/desorption isotherms, thermogravimetric analysis (TGA), Raman spectroscopy and, scanning electron microscopy (SEM). Catalytic behavior of the composite material on the advanced photo-Fenton degradation of Amaranth dye was evaluated. The synthesis conditions employed on the microwave system were: temperature (235 °C), power (500 W), pressure (600 psi) and irradiation time (30 min). Characterization results showed the formation of hybrid material, containing a predominantly microporous structure, with surface area and total pore volume of 54 m2 g-1 and 0.2249 cm3 g-1, respectively. The composite exhibited higher catalytic activity compared to the pure NiFe2O4, reaching 100% of decolorization at 60 min of reaction, which can be attributed to a synergism between NiFe2O4 and MWCNTs. Therefore, NiFe2O4/MWCNTs composite can be used as a promising photo-Fenton catalyst to degrade Amaranth dye from aqueous solutions.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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
