摘要
通过超声处理将Fe_3O_4微球颗粒负载在具有大比表面积的氧化石墨烯(Graphene Oxide,GO)表面,成功合成了Fe_3O_4微球/氧化石墨烯复合物(Fe_3O_4-GO),并将该复合物应用于有机酚类化合物的测定分析。首先根据Hummers法制备了GO;然后使用溶剂热法制备了粒径200 nm左右的Fe_3O_4微球;最后用扫描电子显微镜对材料的形貌结构进行探索。结果表明,该合成方法简单有效,制备的复合物能够有效地应用于电化学传感器的构建,并对有机酚类化合物进行检测分析。
This paper designed a simple method to fabricate Fe3O4 microsphere-graphene oxide (Fe3O4-GO) composite which is applied for the determination of phenolic compound. The Fe3O4 mierospheres were well-distributed on the graphene oxide (GO) surface after ultrasonic treatment. GO was synthesized from natural graphite flakes by the hummers method. Fe3O4 microspheres about 200 nm in diameter were synthesized by the solvothermal method, and scanning electron microscopy (SEM) was used to explore the morphology of Fe3O4-GO. This work showed that the approach is simple and effective for the preparation of Fe3O4 -GO, which can be effectively applied to detect the phenolic compounds.
