Magnetic and photo-catalyst BaFe_(12)O_(19)-ZnO: Hydrothermal preparation of barium ferrite nanoparticles and hexagonal zinc oxide nanostructures

摘要

The present work shows preparation of barium ferrite nanoparticles, hexagonal zinc oxide and BaFe_(12)O_(19)/ ZnO nanocomposites as effective photocatalysts synthesized by hydrothermal method. The influence of various surfactants on morphology and particle size was studied. The prepared products were characterized by X-ray diffraction pattern (XRD), scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Alternating gradient force magnetometer (AGFM) illustrated ferromagnetic behaviour of BaFe_(12)O_(19) nanoparticles. The photocatalytic behaviour of BaFe_(12)O_(19)-ZnO nanocomposites was evaluated using the degradation of acid blue, acid brown, acid black and congored under ultraviolet light irradiation. The results show that nanocomposites have applicable magnetic and photocatalytic performance.
