摘要 采用简单绿色的方法,在不加任何连接剂的情况下制备绒球状的多孔Fe3O4@Cu2O核壳纳米复合物.通过SEM、XRD、UV-Vis、BET以及精密SQUID磁学等手段对所制备产物的形貌、晶型、组成、比表面积以及磁性等进行分析.结果表明,这种结构新颖的多孔Fe3O4@Cu2O纳米复合物具有超顺磁性,在可见光下具有很好的光催化甲基橙(MO)降解的性能和循环稳定性,因此在环境净化方面具有潜在的应用价值. The Fe3O4@Cu2O nanocomposite microspheres were successfully synthesized by a facile, green route without any linkers. The morphology, crystallinity, composition, specific surface area and magnetism of the as-prepared composites were characterized by SEM, XRD, UV-Vis, BET, SQUID and so on. The results indicate that this novel porous Fe3O4@Cu2O nanocomposites are superparamagnetic and show efficient photocatalytic activity and high cycling stability while photocatalytic degradation of methyl orange （MO） under visible light irradiation. The composites will have potential applications in the environmental cleaning under sunlight.
