Synthesis and characterization of ZnxMn(1–x)Fe2O4

ZnxMn(1–x)Fe2O4 nanoparticles were successfully prepared in the isopropanol solvent with the hydrothermal method and the hydrothermal method combined with impregnation. The characterization of the samples by using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier Transform Infrared (FTIR), and surface area analysis (BET) was conducted. The samples synthesized with the hydrothermal method had a phase composition of franklinite (Zn,Mn,Fe)(Fe,Mn)2O4. Meanwhile, the samples synthesized with the hydrothermal method combined with impregnation had the main phase composition of ZnxMn(1–x)Fe2O4. The Zn0.8Mn0.2Fe2O4 (ZnFe2O4/MnSO4 molar ratio = 4:1) sample exhibited the highest degree of structural order, with a BET surface area of 25.7 m2/g.
