Photo-degradation of methylene blue: photocatalyst and magnetic investigation of Fe۲O۳–TiO۲ nanoparticles and nanocomposites

چکیده مقاله

In this work at the first step Fe2O3 nanoparticles were synthesized via a fast microwave method. Then Fe2O3–TiO2 nanocomposites were synthesized by a sonochemical-assisted method. The prepared products were characterized by X-ray diffraction pattern, scanning electron microscopy, transmission electron microscopy and Fourier transform infrared spectroscopy. Alternating gradient force magnetometer illustrated super-paramagnetic property of Fe2O3 nanoparticles. The photocatalytic behaviour of Fe2O3–TiO2 nanocomposites was investigated using the degradation of methylene blue under ultraviolet light irradiation. The outcomes confirm that nanocomposites have applicable magnetic and photocatalytic performance. Fe2O3–TiO2 nanostructures were added to cellulose acetate and because of presence of nano-additives properties of polymeric matrix like flame retardancy were increased.
