Green synthesis and Characterization of NiFe۲O۴-ZnS : photo catalyst and magnetic investigation of nanocomposites.

NiFe۲O۴ nanoparticles were first synthesized via a simple precipitation method. Then NiFe۲O۴-ZnS nanocomposites were prepared by a fast chemical procedure. The prepared products were characterized by X-ray diffraction, scanning electron microscopy and fourier transform infrared spectroscopy. Alternating gradient force magnetometer was used to study the magnetic property of the products. The results illustrated superparamagnetic behaviour of NiFe۲O۴ nanoparticles. The photo-catalytic behaviour of NiFe۲O۴–ZnS nanocomposites was evaluated using the degradation of two various azo dyes under ultraviolet light irradiation. The results show that nanocomposites have applicable magnetic and photocatalytic performance.
