Reduced graphene oxide (rGO)-assisted microwave (MW) synthesis of metal-oxide-based binary and ternary nanocomposites has recently gained considerable research attention. In this context, the current work demonstrates a facile rGO-supported solid-state MW synthetic route for fabricating a ternary nanocomposite of VO, FeO, and rGO. Here, the MW irradiation for 90 s was found to be suitable for the reduction and exfoliation of graphite oxide to form rGO, the reduction of VO to form VO and the formation of FeO from ferrocene. X-ray diffraction and X-ray photoelectron spectroscopy analyses confirm the formation of distinct metal oxides in the presence of rGO. Furthermore, the morphological analysis reveals the deposition of FeO nanoparticles and VO nanorods on the 2D rGO surface. Notably, the ternary composite displayed good magnetic properties for its potential biomedical applications. Overall, this work explores an efficient and cost-effective synthetic approach for developing graphene-based magnetic nanocomposites.
还原氧化石墨烯(rGO)辅助微波(MW)合成金属氧化物基二元和三元纳米复合材料最近受到了相当多的研究关注。在此背景下,当前工作展示了一种简便的rGO负载固态MW合成路线,用于制备VO、FeO和rGO的三元纳米复合材料。在此,发现90秒的MW辐照适用于将氧化石墨还原和剥离以形成rGO,将VO还原以形成VO以及由二茂铁形成FeO。X射线衍射和X射线光电子能谱分析证实了在rGO存在下形成了不同的金属氧化物。此外,形态分析揭示了FeO纳米颗粒和VO纳米棒沉积在二维rGO表面上。值得注意的是,该三元复合材料因其潜在的生物医学应用而显示出良好的磁性。总体而言,这项工作探索了一种高效且经济高效的合成方法来开发基于石墨烯的磁性纳米复合材料。
