Source abstract
Abstract
Abstract Magnetic Co x Zn 1− x Fe 2 O 4 nanoparticles and Co x Zn 1− x Fe 2 O 4 -graphene nano-heterostructures were prepared by chemical co-precipitation route and ultra-sonication method respectively. The characterization of Co x Zn 1− x Fe 2 O 4 nanoparticles was carried out by thermo-gravimetric analysis (TGA), X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy, vibrating sample magnetometry (VSM). TGA predicted the phase formation temperature around 850 °C. XRD and FTIR confirmed the single phase cubic structure. Crystallite size as calculated by Scherrer׳s formula was found 50–70 nm; however the nanoparticles size determined by TEM was found 35–75 nm. VSM confirmed the ferromagnetic nature of both ZnFe 2 O 4 and Co 0.3 Zn 0.7 Fe 2 O 4 nanoparticles. The reduced graphene oxide (rGO) prepared by modified Hummer׳s method was characterized by UV–visible (UV–vis) spectroscopy and XRD. As prepared rGO was utilized for preparation of Co x Zn 1− x Fe 2 O 4 -rGO nano-heterostructures. SEM confirmed the well dispersed Co x Zn 1− x Fe 2 O 4 nanoparticles among rGO sheets. Electrochemical impedance spectroscopy (EIS) studies of Co x Zn 1− x Fe 2 O 4 nanoparticles and their nano-heterostructures with rGO showed that Co x Zn 1− x Fe 2 O 4 nanoparticles exhibit the high charge transfer resistance as compared to nano-heterostructures. The photocatalytic efficiency of Co x Zn 1− x Fe 2 O 4 nanoparticles and their nanocomposites with rGO was evaluated using methylene blue as model organic compound in the presence of visible light. The Co x Zn 1− x Fe 2 O 4 -rGO nano-heterostructures showed more efficiency as compared to Co x Zn 1− x Fe 2 O 4 nanoparticles. The ferrite nanoparticles and their nano-heterostructures with rGO could be separated and recycled by conventional magnetic bars easily.
