摘要

本文介绍了共沉淀法合成磁铁矿-氧化石墨烯纳米复合材料的合成和表征的研究进展。采用x射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、透射电镜(TEM)和振动样品磁强计(VSM)分析了其结构和理化性质。XRD和FT-IR分析证实得到了磁铁矿。XRD分析表明，当氧化石墨烯(GO)存在时，纳米颗粒的平均尺寸减小。透射电镜显示，氧化石墨烯表面有磁铁矿修饰，VSM表现出超顺磁性。

Synthesis and characterization of magnetite-graphene oxide nanocomposite

This work presents the advances in the synthesis and characterization of magnetite-graphene oxide nanocomposite synthetized by coprecipitation. Structural and physicochemical properties were analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). XRD and FT-IR analyses corroborated that magnetite was obtained. Nanoparticle mean size from XRD analysis revealed that it decreased when graphene oxide (GO) was present. TEM displayed that magnetite decorates the GO and VSM revealed superparamagnetic behavior.
