Influence of Synthesis Temperature on Magnetic and Adsorption Properties of Nickel–Zinc Ferrite Nanoparticles by Microwave Hydrothermal Method

Abstract:

The microwave hydrothermal method was applied in the synthesis of Ni_0.5Zn_0.5Fe₂ O₄ ferrite nanoparticle. X-ray diffraction (XRD), infrared spectroscopy (IR) were conducted to characterize the as-prepared samples. The experiment results revealed the as-prepared nanoparticle was 8.50-10.3 nm in size with various synthesis temperatures from 40-120°C, and synthesis temperature had effects on the magnetic and adsorption properties of Ni_0.5Zn_0.5Fe₂ O₄. The saturation magnetization values increased from 22.6 to 90.8 emu g^-1 with synthesis temperature increasing. Moreover, synthesis temperature also influences the adsorption capacity of methyl orange (MO) on Ni_0.5Zn_0.5Fe₂ O₄. The as-prepared Ni_0.5Zn_0.5Fe₂ O₄ showed the highest adsorption capacity of MO in the current work when synthesis temperature was 80°C, which was contributed to the more adsorption site distributed on the nanoparticle.
