摘　　要：四氧化三铁是一种常见的磁性纳米材料,纳米银是一种常见的贵金属纳米材料,它们都具有广泛的应用。在该研究中,首先以硫酸亚铁和三氯化铁为原料,以氨水为沉淀剂,采用共沉淀法合成磁性的四氧化三铁纳米材料。并以聚乙烯吡咯烷酮(PVP)作为分散剂,乙二醇作为还原剂和硝酸银进行反应,来制备银纳米材料。在此基础上,通过三种方法来制备磁性Fe_(3)O_(4)/Ag复合纳米材料。最后,将合成的复合纳米材料借助X射线衍射(XRD)、红外光谱法和紫外可见吸收光谱法等技术对其进行了表征。Ferric oxide nanoparticle is common magnetic nanomaterial,silver nanoparticle is a common noble nanomaterial,they have a large number of applications.In the study,magnetic ferroferric oxide nanomaterials were synthesized by coprecipitation method,ferrous sulfate and ferric chloride were employed as raw materials,and ammonia was used as the precipitating agent.The silver nanomaterials were obtained by using polyvinylpyrrolidone(PVP)as dispersant,and ethylene glycol as reducing agent to react with silver nitrate to prepare Ag nanoparticles.Then,three methods were employed to prepare magnetic Fe_(3)O_(4)/Ag composite nanomaterials based on that base.Finally,the synthesized composite nanomaterials were characterized by X-ray diffraction(XRD),infrared spectroscopy and ultraviolet-visible absorption spectroscopy.
