Abstract Over the past decades, graphene oxide (GO) and its composites with organic and inorganic components have gradually become one of the most popular carbon nanomaterials, on account of multitudinous advantages, including great conductivity, excellent thermal stability and large specific surface area. In particular, the magnetic GO based composites have been extensively investigated for various applications owing to their combined advantages from both GO and magnetic nanoparticles. Although many strategies have been developed for preparation of magnetic GO based composites, a facile and efficient strategy is still rarely reported. In this work, we developed a direct, ultrafast, green and non-toxic strategy for scalable production of GO–Fe3O4 hybrids for the first time. Compared with conventional preparation methods, this strategy only requires a simple one-step reaction and would produce no pollutants in the whole reaction process. Furthermore, it could convincingly demonstrate the successful preparation of GO–Fe3O4 hybrids with outstanding properties through a series of characterization techniques. Finally, the outstanding performance of GO–Fe3O4 hybrids in adsorption experiments has been also demonstrated. Results indicated that these GO–Fe3O4 composites are potentially used for environmental adsorption.

一种制备磁性氧化石墨烯复合材料的简便策略及其环境吸附潜力

摘要 在过去的几十年里，氧化石墨烯（GO）及其有机和无机组分的复合材料由于具有导电性好、热稳定性好和比表面积大等众多优点，逐渐成为最受欢迎的碳纳米材料之一。特别是，由于 GO 和磁性纳米粒子的综合优势，磁性 GO 基复合材料已被广泛研究用于各种应用。尽管已经开发了许多用于制备磁性 GO 基复合材料的策略，但仍然很少报道简单有效的策略。在这项工作中，我们首次开发了一种直接、超快、绿色和无毒的策略，用于可规模化生产 GO-Fe3O4 杂化物。与常规制备方法相比，这种策略只需要简单的一步反应，整个反应过程不会产生污染物。此外，它可以通过一系列表征技术令人信服地证明成功制备具有优异性能的 GO-Fe3O4 杂化物。最后，GO-Fe3O4 杂化物在吸附实验中的出色性能也得到了证明。结果表明，这些 GO-Fe3O4 复合材料有可能用于环境吸附。GO-Fe3O4 杂化物在吸附实验中的出色性能也得到了证明。结果表明，这些 GO-Fe3O4 复合材料有可能用于环境吸附。GO-Fe3O4 杂化物在吸附实验中的出色性能也得到了证明。结果表明，这些 GO-Fe3O4 复合材料有可能用于环境吸附。
