Preparation and Physicochemical Characterization of Magnetic Composite: CuFe2O4 / Layered Double Hydroxide

We fabricated new magnetic material CuFe₂O₄/Zn₂Cr-LDH by the combination of CuFe₂O₄ and layered double hydroxide (LDH) through two steps. CuFe₂O₄ was prepared by sol-gel method with the assistant of citric acid, which was used in synthesis of the composite via microwave hydrothermal method subsequently. The physicochemical properties of the composite was characterized by several techniques, such as X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Vibrating sample magnetometer (VSM) and Thermogravimetry-differential thermal analysis (TG-DTA). The magnetic composite reveals several advantage of LDH structure and spinel ferrite oxide and is potential for the application of heterogeneous catalysis.
