我们将CuFe2O4与层状双氢氧化物（LDH）结合，通过两步制备了新型磁性材料CuFe2O4/Zn2Cr-LDH。以柠檬酸为辅助剂，采用溶胶-凝胶法制备了CuFe2O4，随后用于微波水热法合成该复合材料。通过X射线衍射（XRD）、傅里叶变换红外（FT-IR）光谱、振动样品磁力计（VSM）和热重-差热分析（TG-DTA）等技术对复合材料的物理化学性能进行了表征。该磁性复合材料展现了LDH结构和尖晶石铁氧体氧化物的多种优点，具有多相催化应用的潜力。
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.
