摘要
Spinel nickel doped magnesium zinc ferrite nanoparticles under different substitutions have been prepared using co-precipitation technique. The characterization studies which include crystallite size, crystalline solid structure and optical properties of the prepared nanoparticles were examined using x-ray diffraction (XRD), fourier transmission infrared spectrum (FTIR), scanning electron microscope (SEM) and absorbance that was measured by ultraviolet visible (UV) spectroscopy. As increasing the Ni concentration, the optical band gap increases from 3.32 eV to 4.57 eV. In this research work, the photocatalytic assessment of Ni-added-Mg-Zn nano-ferrites has been investigated by using bulb light degradation (methylene blue dye (60 W) method. Mg0.5Zn0.5-xNixFe2O4 spinel nano-ferrites (x = 0.125, 0.250, 0.375) were produced by co-precipitation method. The photocatalytic study has been reported by analyzing the degradation of methylene blue dye under sunlight irradiation. The better-quality photocatalytic activity with increased Ni content was investigated for the samples under study for a 40-minute exposure of × = 0.125, a maximum degradation efficiency of 61 precent was acquired. The phase-change was appeared due to shifting of peaks to the higher angle in Mg-Zn ferrite samples as a result of increments in Ni contents. According to vegard's law, the lattice parameter (a) of the crystal increases with increasing the concentration of nickel ion. Phase identification of magnesium-zinc ferrite nanoparticle was done by using X-ray diffraction (XRD).
